INSTALLING POTPOURRI
PC Requirements
Your PC must have a color monitor and a hard disk.
Backing Up Potpourri Master Disk
Before starting the installation of Potpourri, make a working copy
of the master by using the DOS DISKCOPY command. Type:
DISKCOPY A: A:
Put the original disk in a safe place and use the working copy for
installing Potpourri.
Installation Procedure
Insert the working copy into disk drive A. Type:
A:INSTALL
Potpourri is now installed. Place the working copy in a safe place.
The INSTALL.BAT file created the \OGHAM directory on disk drive C
and loaded all of the Potpourri files into the \OGHAM directory.
If you did not have an AUTOEXEC.BAT file, INSTALL created one for
you. If there was an AUTOEXEC.BAT file, please edit the file and
add ;\OGHAM to the PATH line or if a PATH line does not exist, enter
a new line PATH C:\;\OGHAM. Add a last line to the file and type in
OGHAM as this is the executable name for Potpourri.
If you are not familiar with AUTOEXEC.BAT, this is a special file
that is executed when the power switch is turned on or when you
hold down the three keys Ctrl Alt Del.
You are ready to enter Potpourri. Type:
AUTOEXEC
The first menu you should use is the Explain Menu. All of the
documentation for Potpourri resides within this menu screen.

Potpourri Menu Program
Introduction
The Potpourri install feature established a \OGHAM directory and loaded all
of the files into this directory. An additional requirement was the entry
of \OGHAM on the PATH line of the AUTOEXEC.BAT file. The minimum of the
PATH line would be PATH C:\;\OGHAM . Entry of OGHAM on the last line
of the AUTOEXEC.BAT file allows for the automatic execution of Potpourri at
startup. If this line was not entered, execution of Potpourri can be done
by typing OGHAM.
Do not turn the computer off while in Potpourri, as the program is controlling
the environment. Exit Potpourri with the Esc key and the required data will
be contained on disk files.
Use of the special keys for selection of an item:
1) The menu screen request - select action by function key - requires
the pressing of the F1 through F10 keys. In some cases, the select-
ion requires holding the Alt key down and pressing a function key.
2) To move to a different menu screen or to exit from the program - Use
Esc key - press the Esc key.
3) Sub-menus have - select with cursor keys - and requires the use of
the up arrow, left arrow, down arrow and right arrow keys for
selecting an item.
4) The <cr> is the carriage return (enter) key which is the bold left
arrow with the short vertical line attached on the tail of the
arrow.
5) In some cases, the message - press any key to continue - will
appear and is used for error messages and return from an idle
state. Press any key and the program will continue.
Entering a response to a prompt requires the use of <cr> when more than one
keystroke is required such as in responding to Enter date (1-31). A <cr> is
not required if the prompt request that you press a key such as in Press Y
for Yes or N for No. The prompt will guide you by the keyword:
Enter ( requires a <cr> )
Press ( does not require a <cr> ).
You may type alphabetic uppercase or lowercase in all of your responses to
the prompts.
If a typing mistake is made prior to <cr>, use the Backspace key to make the
correction. The Backspace key is the bold left arrow located on the top row
of the keyboard next to NumLock.
To print the screen contents to the printer, hold the Shift key down and
press the PrtSc key. There are two Shift keys, one is located to the right
of the / key and the other is located to the left of the \ key. To print a
graphic screen such as in Doodle, the system GRAPHICS program must be loaded.
This program will be loaded at start up if the Potpourri Install program
created the AUTOEXEC.BAT file.
Potpourri Menu
The Potpourri menu itemizes all of the menus that can be selected by pressing
of a function key and allows you to navigate among the various menus. Each
of these menus returns to the Potpourri menu by pressing the Esc key. The
Esc key on the Potpourri menu is used to exit from the Potpourri program.
You can also add four additional menus to the Potpourri menu screen and
function keys 7 through 10 will be assigned to these specialized menus. The
documentation for adding menus and items on a menu screen is covered under
the Explain Menu.
Potpourri Menu F1 - - Explain Menu
In most cases, documentation is not required as the selection and subsequent
prompts will guide you. There are various parts of the program that do
require additional information and to that extent, the Explain menu can be
called upon to furnish the documentation. You should list the documentation
for Doodle, as the various keys required for the manipulation of Doodle is
difficult to memorize and the use of the keys only appears in the documem-
tation.
The Explain menu has disk files associated with each function key. These files
contain the documentation that you can select either to be displayed on the
screen or printed.
Potpourri Menu F2 - - Menu Changes
You have complete control over four menus. Each of these menus can have up to
twenty items. Documentation for menu changes is contained within the Explain
menu.
Potpourri Menu F3 - - DOS Commands
Listed on the DOS Commands menu are the various commands for control of the
operating system. Selection of a directory or a file is by use of a secondary
screen that list the directories or the files contained within the selected
directory. Selection on the secondary screen is made by placing the cursor at
the required directory/file and pressing <cr>. The current directory and
selected file is displayed on the bottom line of the DOS Command menu screen.
The first selection of the F1 key of the DOS Commands menu (Change directory
/display directories), creates a file for all directories. Use F2 key and
F3 key of the DOS Commands menu for creating and removing directories. Do not
make changes to the directories outside of the Potpourri program.
Potpourri Menu F4 - - Personal Secretary
To avoid a burn in of a menu screen image, the screen will blank out if the
program is idle for a period exceeding five minutes and every five minutes a
clock will appear on the screen. Every half hour chimes will play and on the
hour the hour will sound. The F1 key on the Personal Secretary Menu can be
toggled to turn chimes off or on. Pressing any key while in the idle stage
(screen is blank or with a clock) will return the screen back to the menu.
Potpourri Menu F5 - - Relaxation
You can place popular songs into files and play these songs. Three octaves are
used and you can select the tempo for playing a song.
The F3 key -Relax and enjoy - plays background classical music (1812 Overture
and the William Tell Overture) while graphics are drawn on the screen.
Potpourri Menu F6 - - Execute Programs
Programs have a file extension of .EXE or .COM. In addition, the file
extension of .BAT can also be used for the file (program) being displayed on
the bottom line of the screen.

Menu Udating
The menus supplied with the system cannot be altered. You have the capability
to add four new menus. Each of your menus can have up to twenty item lines.
Maximun length of entry for menu and item is 60 characters.
The F1 key is used for adding a new menu. The name that you type will appear
on the Potpourri menu and will also be the title of the menu screen.
After the assignment of a menu, use the F3 key for adding items. These items
can be a command i.e. COPY *.BAS \NEWDIR, an execution EDLIN MYFILE.TXT or the
use of a .BAT file i.e. EDIT MYFILE.TXT. The item must be a complete statement
and contained on one line.
While in the Menu Changes menu, you will be prompted to supply the required
data.
Again, a reminder, do not turn the computer off when in Potpourri. Exit
from Potpourri with the Esc key then turn power off. If you don't, all of
the additions/changes you made will not be recorded.

Appointment Calendar
The program allows up to twelve months of appointment calendars by using a
twelve month moving cycle. The months for next year are less than the current
month and the months for the previous year are greater than than the current
month i.e. if current month is June, next year months can be January through
May and previous year months can be July through December.
Each month has a separate file with a file name APPOINT. The file extension
is 1 for January and 12 for December. June appointment calendar file would
be named APPOINT.6. If a new month assignment is made and the file for that
month already exists, the existing file is deleted. If you wish to retain
the existing file, use the DOS Command menu to select by the F1 key the OGHAM
directory and copy the file by use of the F6 key.
Prompts will guide you in the operation of the Appointment Calendar program.
When all the appointments are made for a particular day, selecting by cursor
New Date or pressing the Esc key will cause the current day appointments to be
written to the APPOINT file.

COMPUTER SCIENCE CALCULATOR
Introduction
The Computer Science Calculator is listed on the Personal Secretary Menu
screem. From the Potpourri Menu, press F4 key to enter the Personal Secretary
Menu. Press F9 key to enter the Computer Science Calculator program.
The Computer Science Calulator has been designed for the student learning the
microcomputer and for the professional programmer writing system or application
programs. The unique features allows one to use the calulator without the
constant referral to a User's Guide.
The Computer Science Calculator provides three modes of operation:
* Integer
* Real (floating point) arithmetic
* Keyboard interpretation
Integer mode has four number bases - decimal, binary, hexadecimal and
octal - with one's or two's complement and unsigned capability. Logical,
arithmetic and bit manipulations is provided in this mode. The counter
window is user controlled and can vary from four (4) positions to 52 positions.
Real mode allows decimal point and single-precision decimal
entries and stores the values in double-precision format.
Results can be displayed in binary representation.
Keyboard interpretation converts entered ASCII code to character or entered
character to ASCII code and will display extended and control character
information.
Error conditions are provided in all three modes. The bottom line of the
screen is used for the error message. If an error occurs, the message will
remain on the screen until a key is pressed.
GETTING STARTED
Enter the Computer Science Calculator by the Personal Secretary Menu function
key 9.
Take a few moments to look over the screen.
The three blocks - Decimal, Integer and 2's - are in reversed color. The
reversed color is a reminder for the current mode of operation, number base
and complement.
The top rectangular block is the window of the x register. In integer mode
the window size can vary from four (4) positions to 52 positions.
Regardless of the number base in use, an error will result if the integer
entered exceeds the window size of the binary representation of the integer.
The number 8 in brackets following the block labeled Length is the current
window size. The size is for both x and y registers.
Each word or character within a block is a function of the Computer Science
Calculator. Notice that the first character of a word within a block is either
upper case (as in Decimal) or lower case (as in octal). To select a function,
you type the first character of the word as shown.
For blocks that are attached (rotate - left - right), you are required to
enter two (2) keystrokes. The first key will select the function and the
second key is the action to be taken.
The bottom display line is used for reporting errors and action to be taken.
This line is also used for instructions to exit the program or to change to
a different mode.
One more bit of information before starting. The carriage return bar on the
keyboard has been labeled many different ways. The Computer Science Calculator
presents this bar as the back arrow with a half of a tail and the word enter.
For the examples in the User's Guide the <enter> is used when the carriage
return bar is to be pressed.
Get acquaninted session:
Type 12
Type B (Binary)
Type H (Hexadecimal)
When in hexadecimal, lower case letters a through f are printed. You must
type lower case letters for hexadecimal numbers.
Type o (octal)
Type L (Length)
The Length of the window (x register) and the y register has been changed to
12 and the registers have been set to zero.
Type K (Keyboard)
Type 7
Type A (ASCII)
Press Esc and then R
Type 12.25
Type I (Integer)
The Computer Science Calculator resets to the initial stage each time you
change mode of operation.
Type B (Binary)
Type 3
The error message will be erased after:
Type 11
Type <enter>
This is <enter> first role, the x register is transferred to the y register
and the x register is set to zero.
Type D (Decimal)
Type 24
Type W (Window)
Type P (Previous)
Type <enter>
This is <enter> second role. When two keystrokes are used for a function, the
<enter> allows an exit from the function. Other keystrokes will also allow an
escape, but to be consistent use <enter>.
Type + (addition)
The arithmetic result is placed in the x register. More will be said about
reversed polish notation in the arithmetic operations section.
Type C (Clear)
The x register and y register have been cleared.
ARITHMETIC OPERATIONS
This is a general description that applies to both Integer and Real modes.
Arithmetic operations are performed by reversed polish notation. The operands
(x and y) are separated by <enter> and then the operator key is pressed.
The x and y registers are used in the arithmetic operations as shown in the
expressions of the following table. The arithmetic operators are identified
on the screen as:
OPERATION OPERATOR REGISTERS
Multiplication x (lower case) X x Y
Addition + X + Y
Subtration - X - Y
Division / X / Y
In addition to the above arithmetic operators, there are two operators that
apply to Integer mode.
Exponentiation ^ (shifted 6 key) X ^ Y
Remainder Modulo X MOD Y
The use of the x and y registers is shown in the following examples for
integer mode.
Integer mode arithmetic requires that complement must be set to 2's.
Type I (Integer mode)
Type s (set complement)
Type 2 (two's complement)
Division example:
To divide 34 by 5 in Integer mode:
Type 5 (divisor)
Type <enter> (place divisor in y register)
Type 34 (dividend in x register)
Type / (division X/Y)
Window (x register) displays the quotient.
In Integer mode, the quotient is
truncated and you can use Modulo (type M) to obtain the remainder.
Modulo example:
To obtain the remainder for the above example:
Type C (Clear)
Type 5
Type <enter>
Type 34
Type M (Modulo X MOD Y)
Window displays the remainder.
The arithmetic operator is keyed in last in reversed polish notation. This
also allows repetitive arithmetic operations. Using the result of the last
example, the value 5 is in the y register and the value 4 is in the x register.
Multiplication example:
Type x (multiplication X x Y)
Type x (multiplication X x Y)
Sign change
To change the sign of the value in the window, type S.
Subtractation example:
Type C (Clear)
Type 25
Type S (Sign change)
Type <enter>
Type 15
Type - (subtraction X-Y)
Addition example:
Type S (Sign change)
Type <enter>
Type 15
Type + (addition X+Y)
Exponentiation example:
Raise 2 to the power of 6
Type C (Clear)
Type 6

Type <enter>
Type 2
Type x (multiplication X x Y)
or
Type C (Clear)
Type 1225E-2
Type <enter>
Type 2
Type x (multiplication X x Y)
INTEGER MODE
The Computer Science Calculator stores the integer in binary representation for
both the x and y registers. This is the reason for the error of exceeding
length of the window. There is also a warning of positive to negative and this
occurs when keying in an integer and the high order position (bit) of the
window becomes a one.
Number Bases
Select the number base by typing in the first character of the word as shown
in the number base block.
Type D for decimal - accepts digits 0 through 9.
Type B for binary - accepts digits 0 and 1.
Type H for hexadecimal - accepts digits 0 through 9 and
lower case letters a through f.
Type o for octal - accepts digits 0 through 7.
All of the number bases can be used for a function. For two number operators,
such as arithmetic operations, you can type in an integer ,enter the value into
the y register and then change to another number base for the x register. The
only limitation is the value of a number cannot exceed the length of binary
representation of that number.
Type I (Integer mode)
Type 8
Type L (Length)
Type H (Hexadecimal)
Type ad (-83 in decimal)
Type <enter>
Type D (Decimal)
Type 15
Type + (addition)
Window control
The window control is used for displaying the previous entered integer (-83)
which is in the y register, the current integer (-68) which is the x register
and allows the interchange of registers by the use of swap.
Using the above example:
Type W (window control)
Type P (previous)
Type S (swap)
Type <enter> (escape from window control)
Window (x register) displays -83.
Clear
Type C to clear the x and y registers.
Sign change
Type S to change the sign of the value in the window (x register). Set
compliment must be 1's or 2's or an error message will be displayed.
Length
Type in the length required for the x and y registers. Type L and the window
size will be changed and the size will print in brackets alongside of the
Length block. Size can vary from four (4) positions to 52 positions.
In binary, each position within the registers is called a bit. And a byte is
eight (8) bits. One half of a byte (4 bits) is a nibble. Two bytes (16
bits) is a word. Four bytes (32 bits) is a doubleword. These four lengths
are the various lengths for the microcomputers. For the purist, there is
also a length of 20 bits formed by combining a segment value (offset by
hexadecimal 0) with an offset value to obtain the effective address of the
microcomputer's memory.
set compliment
For this section, the window is eight (8) positions in length.
Type I (Integer mode)
Type D (Decimal)
Type 8
Type L (Length)
In one's or two's complement, a negative integer is recognized by a one in
the high order position of the binary representation of the integer displayed
in the window. In one's complement, a zero can also be a minus zero and this
was the reason two's complement was invented. When a negative number is used
in one's complement, arithmetic results can be erroneous.
Positive integers are represented in the correct binary form.
Type 3
Type B (Binary)
Negative integers are represented by complementing each bit.
Type s (set complement)
Type 1
Type S (Sign change)
One's complement in binary form of -3.
Type D (Decimal)
There is a difference in representing negative integers in
two's complement.
Type C (Clear)
Type 3
Type B (Binary)
Negative integers are first complemented as in one's complement and then a
one is added.
Type s (set complement)
Type 2
Type S (Sign change)
Two's complement in binary form of -3.
Unsign is the absolute magnitude of an integer. A one in the
high order bit of the register does not represent a negative integer.
Type C (Clear)
Type s (set complement)
Type u
Type D (Decimal)
Type 255 (largest integer in a byte)
Type B (Binary)
For a byte (8 bits) in two's complement, the positive integer range is 0 to 127
and the negative integer range is -1 to -128.
Type C (Clear)
Type s (set complement)
Type 2
Type D (Decimal)
Type 127
Type B (Binary)
Type C (Clear)
Type D (Decimal)
Type 128
Type B (Binary)
Bit manipulation
For this section, we will again set window size to a byte, use binary
representation and set complement unsign.
Type C (Clear)
Type D (Decimal)
Type 8
Type L (Length)
Type s (set complement)
Type u (unsign)
Type B (binary)
Shift left - Shift right
A shift left can cause an error message of exceeding length of the window.
A binary base shift left is one position, but a hexadecimal base shift left
is four positions.
The -- (key 4 on the numeric pad) is used to shift left and -- (key 6 on the
numeric pad) is used to shift right.
Type 1111
Type -- (shift left)
Type -- (shift left)
Type -- (shift right)
In binary a shift left is multiplication and a shift right is division.
Type C (Clear)
Type 1
Type -- (shift left)
Type D (Decimal)
Type B (Binary)
Type -- (shift left)
Type D (Decimal)
Type B (binary)
Type -- (shift right)
Type D (Decimal)
Rotate
Unlike shifting, the rotated bit is placed in the carry. When you type R,
the carry is set to zero. Rotate left shifts the bits one position to the
left and the carry bit is placed in the low order of the window. The bit
shifted off of the high order position is placed in the carry.
Type C (Clear)
Type s (set complement)
Type u (unsign)
Type B (Binary)
Type 11111111
Type r (rotate)
Type l (rotate left)
Type l (rotate left)
Type <enter> (escape from rotate)
Rotate right shifts the bits one position to the right. The carry bit is
placed in the high order bit of the window and the bit dropped from the low
order position of the window is placed in the carry.
Type C (Clear)
Type 11111111
Type r (rotate)
Type r (rotate right)
Type r (rotate right)
Type <enter> (escape from rotate)
All number bases can be used for bit manipulation, experiment and see what
happens.
Logical operators
As with arithmetic operations, the logical operators that required two
operands are performed by reversed polish notation. The operands are
separated by <enter> and then the logical key is pressed. Not is the only
logical operator that has one operand.
For this section, set window size to a byte, set number base to binary and
the set complement must be unsign.
Type C (Clear)
Type D (Decimal)
Type 8
Type L (Length)
Type s (set complement)
Type u (unsign)
Type B (Binary)
And
And is the logical product. The test reguires that the bit position of the x
and y registers are 1 for the result of that bit position to be 1 else the
bit position is 0. This feature is called "masking" and is used to zero out
unwanted one bits within a byte or whatever length is being tested.
Type 10101010
Type <enter>
Type 11110000 (mask)
Type A (And)
Or
Or is the logical sum. If either of the bit position of the x and y
registers is 1, the result for that bit position will be 1 else the bit
position is 0.
Type C (Clear)
Type 10101010
Type <enter>
Type 11110000
Type O (Or)
Xor
Xor is the logical difference. Xor is "exclusive or" and differs from the
inclusive "or" described above in that only one of the bit position being tested
can be 1 for the result to be 1 otherwise the result is 0.
Type C (Clear)
Type 10101010
Type <enter>
Type 11110000
Type X (Xor)
Not
Not is the logical complement. Not inverts the value of the x register and is
equivalent to an integer multiplied by -1 in one's complement.
Type C (Clear
Type 10101010
Type N (Not)
All number bases may be used for logical operations.
REAL MODE
Real mode allows decimal point and scientific notation (floating point) entries.
A floating point number is represented by an optionally signed integer, a
fraction and an exponent. A decimal point separates the integer from the
fraction. The exponent is optional and is identified by the
digits following the letter E and its sign (+ or -). The E means "times ten
to the power of". Absence of a sign or + sign means move the decimal point to
the right and a - sign means move the decimal point to the left.
Any number from 2.9E-39 to 1.7E+38 (positive or negative) can be represented.
See Arithmetic Operations Section for additional information.
When entering real mode, the window size will be expanded to 64 positions (eight
bytes).
The Computer Science Calculator stores the entered values and the arithmetic
results in double-precision format.
Type R
Type 2
Type S (Sign change)
Type <enter> (place value in y register)
Type .1245E+2
Type / (divide X/Y)
Type B (display result in binary)
Type C (Clear)
Use shift left (key 4 on the numeric pad) to correct an erroneous key entry.
The use of this key will backspace and erase the last entry.
Follow instructions on bottom line of the monitor to exit from real mode.

Executing Programs
Potpourri is not a resident program (does not takeup any of the memory) when
executing programs. There is a small (approx. 1700 bytes) satellite program
that controls the execution of the selected program and returns control to
Potpourri upon the completion of the selected program.
The Executing Programs menu allows a wide latitude of what you can type in.
For instance, if F6 - - Keyin program name - - is selected and File is
None, you could type program name a space and input file name.file extension.
This would be accepted as what you typed in as one variable.

Potpourri Menu Program
Introduction
The Potpourri install feature established a \OGHAM directory and loaded all
of the files into this directory. An additional requirement was the entry
of \OGHAM on the PATH line of the AUTOEXEC.BAT file. The minimum of the
PATH line would be PATH C:\;\OGHAM . Entry of OGHAM on the last line
of the AUTOEXEC.BAT file allows for the automatic execution of Potpourri at
startup. If this line was not entered, execution of Potpourri can be done
by typing OGHAM.
Do not turn the computer off while in Potpourri, as the program is controlling
the environment. Exit Potpourri with the Esc key and the required data will
be contained on disk files.
Use of the special keys for selection of an item:
1) The menu screen request - select action by function key - requires
the pressing of the F1 through F10 keys. In some cases, the select-
ion requires holding the Alt key down and pressing a function key.
2) To move to a different menu screen or to exit from the program - Use
Esc key - press the Esc key.
3) Sub-menus have - select with cursor keys - and requires the use of
the up arrow, left arrow, down arrow and right arrow keys for
selecting an item.
4) The <cr> is the carriage return (enter) key which is the bold left
arrow with the short vertical line attached on the tail of the
arrow.
5) In some cases, the message - press any key to continue - will
appear and is used for error messages and return from an idle
state. Press any key and the program will continue.
Entering a response to a prompt requires the use of <cr> when more than one
keystroke is required such as in responding to Enter date (1-31). A <cr> is
not required if the prompt request that you press a key such as in Press Y
for Yes or N for No. The prompt will guide you by the keyword:
Enter ( requires a <cr> )
Press ( does not require a <cr> ).
You may type alphabetic uppercase or lowercase in all of your responses to
the prompts.
If a typing mistake is made prior to <cr>, use the Backspace key to make the
correction. The Backspace key is the bold left arrow located on the top row
of the keyboard next to NumLock.
To print the screen contents to the printer, hold the Shift key down and
press the PrtSc key. There are two Shift keys, one is located to the right
of the / key and the other is located to the left of the \ key. To print a
graphic screen such as in Doodle, the system GRAPHICS program must be loaded.
This program will be loaded at start up if the Potpourri Install program
created the AUTOEXEC.BAT file.
Potpourri Menu
The Potpourri menu itemizes all of the menus that can be selected by pressing
of a function key and allows you to navigate among the various menus. Each
of these menus returns to the Potpourri menu by pressing the Esc key. The
Esc key on the Potpourri menu is used to exit from the Potpourri program.
You can also add four additional menus to the Potpourri menu screen and
function keys 7 through 10 will be assigned to these specialized menus. The
documentation for adding menus and items on a menu screen is covered under
the Explain Menu.
Potpourri Menu F1 - - Explain Menu
In most cases, documentation is not required as the selection and subsequent
prompts will guide you. There are various parts of the program that do
require additional information and to that extent, the Explain menu can be
called upon to furnish the documentation. You should list the documentation
for Doodle, as the various keys required for the manipulation of Doodle is
difficult to memorize and the use of the keys only appears in the documem-
tation.
The Explain menu has disk files associated with each function key. These files
contain the documentation that you can select either to be displayed on the
screen or printed.
Potpourri Menu F2 - - Menu Changes
You have complete control over four menus. Each of these menus can have up to
twenty items. Documentation for menu changes is contained within the Explain
menu.
Potpourri Menu F3 - - DOS Commands
Listed on the DOS Commands menu are the various commands for control of the
operating system. Selection of a directory or a file is by use of a secondary
screen that list the directories or the files contained within the selected
directory. Selection on the secondary screen is made by placing the cursor at
the required directory/file and pressing <cr>. The current directory and
selected file is displayed on the bottom line of the DOS Command menu screen.
The first selection of the F1 key of the DOS Commands menu (Change directory
/display directories), creates a file for all directories. Use F2 key and
F3 key of the DOS Commands menu for creating and removing directories. Do not
make changes to the directories outside of the Potpourri program.
Potpourri Menu F4 - - Personal Secretary
To avoid a burn in of a menu screen image, the screen will blank out if the
program is idle for a period exceeding five minutes and every five minutes a
clock will appear on the screen. Every half hour chimes will play and on the
hour the hour will sound. The F1 key on the Personal Secretary Menu can be
toggled to turn chimes off or on. Pressing any key while in the idle stage
(screen is blank or with a clock) will return the screen back to the menu.
Potpourri Menu F5 - - Relaxation
You can place popular songs into files and play these songs. Three octaves are
used and you can select the tempo for playing a song.
The F3 key -Relax and enjoy - plays background classical music (1812 Overture
and the William Tell Overture) while graphics are drawn on the screen.
Potpourri Menu F6 - - Execute Programs
Programs have a file extension of .EXE or .COM. In addition, the file
extension of .BAT can also be used for the file (program) being displayed on
the bottom line of the screen.

Appointment Calendar
The program allows up to twelve months of appointment calendars by using a
twelve month moving cycle. The months for next year are less than the current
month and the months for the previous year are greater than than the current
month i.e. if current month is June, next year months can be January through
May and previous year months can be July through December.
Each month has a separate file with a file name APPOINT. The file extension
is 1 for January and 12 for December. June appointment calendar file would
be named APPOINT.6. If a new month assignment is made and the file for that
month already exists, the existing file is deleted. If you wish to retain
the existing file, use the DOS Command menu to select by the F1 key the OGHAM
directory and copy the file by use of the F6 key.
Prompts will guide you in the operation of the Appointment Calendar program.
When all the appointments are made for a particular day, selecting by cursor
New Date or pressing the Esc key will cause the current day appointments to be
written to the APPOINT file.

COMPUTER SCIENCE CALCULATOR
Introduction
The Computer Science Calculator is listed on the Personal Secretary Menu
screem. From the Potpourri Menu, press F4 key to enter the Personal Secretary
Menu. Press F9 key to enter the Computer Science Calculator program.
The Computer Science Calulator has been designed for the student learning the
microcomputer and for the professional programmer writing system or application
programs. The unique features allows one to use the calulator without the
constant referral to a User's Guide.
The Computer Science Calculator provides three modes of operation:
* Integer
* Real (floating point) arithmetic
* Keyboard interpretation
Integer mode has four number bases - decimal, binary, hexadecimal and
octal - with one's or two's complement and unsigned capability. Logical,
arithmetic and bit manipulations is provided in this mode. The counter
window is user controlled and can vary from four (4) positions to 52 positions.
Real mode allows decimal point and single-precision decimal
entries and stores the values in double-precision format.
Results can be displayed in binary representation.
Keyboard interpretation converts entered ASCII code to character or entered
character to ASCII code and will display extended and control character
information.
Error conditions are provided in all three modes. The bottom line of the
screen is used for the error message. If an error occurs, the message will
remain on the screen until a key is pressed.
GETTING STARTED
Enter the Computer Science Calculator by the Personal Secretary Menu function
key 9.
Take a few moments to look over the screen.
The three blocks - Decimal, Integer and 2's - are in reversed color. The
reversed color is a reminder for the current mode of operation, number base
and complement.
The top rectangular block is the window of the x register. In integer mode
the window size can vary from four (4) positions to 52 positions.
Regardless of the number base in use, an error will result if the integer
entered exceeds the window size of the binary representation of the integer.
The number 8 in brackets following the block labeled Length is the current
window size. The size is for both x and y registers.
Each word or character within a block is a function of the Computer Science
Calculator. Notice that the first character of a word within a block is either
upper case (as in Decimal) or lower case (as in octal). To select a function,
you type the first character of the word as shown.
For blocks that are attached (rotate - left - right), you are required to
enter two (2) keystrokes. The first key will select the function and the
second key is the action to be taken.
The bottom display line is used for reporting errors and action to be taken.
This line is also used for instructions to exit the program or to change to
a different mode.
One more bit of information before starting. The carriage return bar on the
keyboard has been labeled many different ways. The Computer Science Calculator
presents this bar as the back arrow with a half of a tail and the word enter.
For the examples in the User's Guide the <enter> is used when the carriage
return bar is to be pressed.
Get acquaninted session:
Type 12
Type B (Binary)
Type H (Hexadecimal)
When in hexadecimal, lower case letters a through f are printed. You must
type lower case letters for hexadecimal numbers.
Type o (octal)
Type L (Length)
The Length of the window (x register) and the y register has been changed to
12 and the registers have been set to zero.
Type K (Keyboard)
Type 7
Type A (ASCII)
Press Esc and then R
Type 12.25
Type I (Integer)
The Computer Science Calculator resets to the initial stage each time you
change mode of operation.
Type B (Binary)
Type 3
The error message will be erased after:
Type 11
Type <enter>
This is <enter> first role, the x register is transferred to the y register
and the x register is set to zero.
Type D (Decimal)
Type 24
Type W (Window)
Type P (Previous)
Type <enter>
This is <enter> second role. When two keystrokes are used for a function, the
<enter> allows an exit from the function. Other keystrokes will also allow an
escape, but to be consistent use <enter>.
Type + (addition)
The arithmetic result is placed in the x register. More will be said about
reversed polish notation in the arithmetic operations section.
Type C (Clear)
The x register and y register have been cleared.
ARITHMETIC OPERATIONS
This is a general description that applies to both Integer and Real modes.
Arithmetic operations are performed by reversed polish notation. The operands
(x and y) are separated by <enter> and then the operator key is pressed.
The x and y registers are used in the arithmetic operations as shown in the
expressions of the following table. The arithmetic operators are identified
on the screen as:
OPERATION OPERATOR REGISTERS
Multiplication x (lower case) X x Y
Addition + X + Y
Subtration - X - Y
Division / X / Y
In addition to the above arithmetic operators, there are two operators that
apply to Integer mode.
Exponentiation ^ (shifted 6 key) X ^ Y
Remainder Modulo X MOD Y
The use of the x and y registers is shown in the following examples for
integer mode.
Integer mode arithmetic requires that complement must be set to 2's.
Type I (Integer mode)
Type s (set complement)
Type 2 (two's complement)
Division example:
To divide 34 by 5 in Integer mode:
Type 5 (divisor)
Type <enter> (place divisor in y register)
Type 34 (dividend in x register)
Type / (division X/Y)
Window (x register) displays the quotient.
In Integer mode, the quotient is
truncated and you can use Modulo (type M) to obtain the remainder.
Modulo example:
To obtain the remainder for the above example:
Type C (Clear)
Type 5
Type <enter>
Type 34
Type M (Modulo X MOD Y)
Window displays the remainder.
The arithmetic operator is keyed in last in reversed polish notation. This
also allows repetitive arithmetic operations. Using the result of the last
example, the value 5 is in the y register and the value 4 is in the x register.
Multiplication example:
Type x (multiplication X x Y)
Type x (multiplication X x Y)
Sign change

INTEGER MODE
The Computer Science Calculator stores the integer in binary representation for
both the x and y registers. This is the reason for the error of exceeding
length of the window. There is also a warning of positive to negative and this
occurs when keying in an integer and the high order position (bit) of the
window becomes a one.
Number Bases
Select the number base by typing in the first character of the word as shown
in the number base block.
Type D for decimal - accepts digits 0 through 9.
Type B for binary - accepts digits 0 and 1.
Type H for hexadecimal - accepts digits 0 through 9 and
lower case letters a through f.
Type o for octal - accepts digits 0 through 7.
All of the number bases can be used for a function. For two number operators,
such as arithmetic operations, you can type in an integer ,enter the value into
the y register and then change to another number base for the x register. The
only limitation is the value of a number cannot exceed the length of binary
representation of that number.
Type I (Integer mode)
Type 8
Type L (Length)
Type H (Hexadecimal)
Type ad (-83 in decimal)
Type <enter>
Type D (Decimal)
Type 15
Type + (addition)
Window control
The window control is used for displaying the previous entered integer (-83)
which is in the y register, the current integer (-68) which is the x register
and allows the interchange of registers by the use of swap.
Using the above example:
Type W (window control)
Type P (previous)
Type S (swap)
Type <enter> (escape from window control)
Window (x register) displays -83.
Clear
Type C to clear the x and y registers.
Sign change
Type S to change the sign of the value in the window (x register). Set
compliment must be 1's or 2's or an error message will be displayed.
Length
Type in the length required for the x and y registers. Type L and the window
size will be changed and the size will print in brackets alongside of the
Length block. Size can vary from four (4) positions to 52 positions.
In binary, each position within the registers is called a bit. And a byte is
eight (8) bits. One half of a byte (4 bits) is a nibble. Two bytes (16
bits) is a word. Four bytes (32 bits) is a doubleword. These four lengths
are the various lengths for the microcomputers. For the purist, there is
also a length of 20 bits formed by combining a segment value (offset by
hexadecimal 0) with an offset value to obtain the effective address of the
microcomputer's memory.
set compliment
For this section, the window is eight (8) positions in length.
Type I (Integer mode)
Type D (Decimal)
Type 8
Type L (Length)
In one's or two's complement, a negative integer is recognized by a one in
the high order position of the binary representation of the integer displayed
in the window. In one's complement, a zero can also be a minus zero and this
was the reason two's complement was invented. When a negative number is used
in one's complement, arithmetic results can be erroneous.
Positive integers are represented in the correct binary form.
Type 3
Type B (Binary)
Negative integers are represented by complementing each bit.
Type s (set complement)
Type 1
Type S (Sign change)
One's complement in binary form of -3.
Type D (Decimal)
There is a difference in representing negative integers in
two's complement.
Type C (Clear)
Type 3
Type B (Binary)
Negative integers are first complemented as in one's complement and then a
one is added.
Type s (set complement)
Type 2
Type S (Sign change)
Two's complement in binary form of -3.
Unsign is the absolute magnitude of an integer. A one in the
high order bit of the register does not represent a negative integer.
Type C (Clear)
Type s (set complement)
Type u
Type D (Decimal)
Type 255 (largest integer in a byte)
Type B (Binary)
For a byte (8 bits) in two's complement, the positive integer range is 0 to 127
and the negative integer range is -1 to -128.
Type C (Clear)
Type s (set complement)
Type 2
Type D (Decimal)
Type 127
Type B (Binary)
Type C (Clear)
Type D (Decimal)
Type 128
Type B (Binary)
Bit manipulation
For this section, we will again set window size to a byte, use binary
representation and set complement unsign.
Type C (Clear)
Type D (Decimal)
Type 8
Type L (Length)
Type s (set complement)
Type u (unsign)
Type B (binary)
Shift left - Shift right
A shift left can cause an error message of exceeding length of the window.
A binary base shift left is one position, but a hexadecimal base shift left
is four positions.
The -- (key 4 on the numeric pad) is used to shift left and -- (key 6 on the
numeric pad) is used to shift right.
Type 1111
Type -- (shift left)
Type -- (shift left)
Type -- (shift right)
In binary a shift left is multiplication and a shift right is division.
Type C (Clear)
Type 1
Type -- (shift left)
Type D (Decimal)
Type B (Binary)
Type -- (shift left)
Type D (Decimal)
Type B (binary)
Type -- (shift right)
Type D (Decimal)
Rotate
Unlike shifting, the rotated bit is placed in the carry. When you type R,
the carry is set to zero. Rotate left shifts the bits one position to the
left and the carry bit is placed in the low order of the window. The bit
shifted off of the high order position is placed in the carry.
Type C (Clear)
Type s (set complement)
Type u (unsign)
Type B (Binary)
Type 11111111
Type r (rotate)
Type l (rotate left)
Type l (rotate left)
Type <enter> (escape from rotate)
Rotate right shifts the bits one position to the right. The carry bit is
placed in the high order bit of the window and the bit dropped from the low
order position of the window is placed in the carry.
Type C (Clear)
Type 11111111
Type r (rotate)
Type r (rotate right)
Type r (rotate right)
Type <enter> (escape from rotate)
All number bases can be used for bit manipulation, experiment and see what
happens.
Logical operators
As with arithmetic operations, the logical operators that required two
operands are performed by reversed polish notation. The operands are
separated by <enter> and then the logical key is pressed. Not is the only
logical operator that has one operand.
For this section, set window size to a byte, set number base to binary and
the set complement must be unsign.
Type C (Clear)
Type D (Decimal)
Type 8
Type L (Length)
Type s (set complement)
Type u (unsign)
Type B (Binary)
And
And is the logical product. The test reguires that the bit position of the x
and y registers are 1 for the result of that bit position to be 1 else the
bit position is 0. This feature is called "masking" and is used to zero out
unwanted one bits within a byte or whatever length is being tested.
Type 10101010
Type <enter>
Type 11110000 (mask)
Type A (And)
Or
Or is the logical sum. If either of the bit position of the x and y
registers is 1, the result for that bit position will be 1 else the bit
position is 0.
Type C (Clear)
Type 10101010
Type <enter>
Type 11110000
Type O (Or)
Xor
Xor is the logical difference. Xor is "exclusive or" and differs from the
inclusive "or" described above in that only one of the bit position being tested
can be 1 for the result to be 1 otherwise the result is 0.
Type C (Clear)
Type 10101010
Type <enter>
Type 11110000
Type X (Xor)
Not
Not is the logical complement. Not inverts the value of the x register and is
equivalent to an integer multiplied by -1 in one's complement.
Type C (Clear
Type 10101010
Type N (Not)
All number bases may be used for logical operations.
REAL MODE
Real mode allows decimal point and scientific notation (floating point) entries.
A floating point number is represented by an optionally signed integer, a
fraction and an exponent. A decimal point separates the integer from the
fraction. The exponent is optional and is identified by the
digits following the letter E and its sign (+ or -). The E means "times ten
to the power of". Absence of a sign or + sign means move the decimal point to
the right and a - sign means move the decimal point to the left.
Any number from 2.9E-39 to 1.7E+38 (positive or negative) can be represented.
See Arithmetic Operations Section for additional information.
When entering real mode, the window size will be expanded to 64 positions (eight
bytes).
The Computer Science Calculator stores the entered values and the arithmetic
results in double-precision format.
Type R
Type 2
Type S (Sign change)
Type <enter> (place value in y register)
Type .1245E+2
Type / (divide X/Y)
Type B (display result in binary)
Type C (Clear)
Use shift left (key 4 on the numeric pad) to correct an erroneous key entry.
The use of this key will backspace and erase the last entry.
Follow instructions on bottom line of the monitor to exit from real mode.

the Potpourri Menu, press F4 key to enter the menu for Personal Secretary.
Press F10 key to enter the Pocket Calculator program.
The program can generate a hard copy of the adding machine tape by creating
a disk file that will contain an exact copy of what appears on the screen
accounting tape. This option is controlled by the user by answering the
question "Do you want a file? Press Y for Yes, N for NO". The response
can be either upper or lower case. If the user requires a hard copy, he can,
after the calculator session, list or display the hard copy file by selecting
the display or print selected file command under the DOS Commands Menu.
The user will also be requested to press the Num Lock key to activate the
numeric key pad located on the right side of the keyboard.
Certain liberties were taken as not all of the caculator symbols are
represented on the keyboard. A legend of keys to be used for these symbols
will always appear on the calculator screen.
Pressing alphabetic keys can be in upper or lower case.

Executing Programs
Potpourri is not a resident program (does not takeup any of the memory) when
executing programs. There is a small (approx. 1700 bytes) satellite program
that controls the execution of the selected program and returns control to
Potpourri upon the completion of the selected program.
The Executing Programs menu allows a wide latitude of what you can type in.
For instance, if F6 - - Keyin program name - - is selected and File is
None, you could type program name a space and input file name.file extension.
This would be accepted as what you typed in as one variable.
