PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 2
Features
--------
- THE FASTEST CREATION AND UPDATING OF ARCHIVES - EVER.
- Higher compression ratios with state-of-the-art Enhanced
Ziv-Lempel-Welch Crunching.
- Unique Archive Commenting capability.
- Data integrity ensured by 16 bit Cyclic Redundancy Check.
- Superior file buffering.
- Not copy protected.
- Pay only if you find the software useful.
Overview
--------
An archive is a collection of one or more files collected into a
single archive file. An file extension of .ARC is usually used to
denote an archive. Each file in an archive is compressed to save
disk space, backup storage space, and file transfer time. When a
file is archived, it is analyzed and compressed with the most
optimal data compression method for that file. Every file in an
archive is stored with a 16-bit Cyclic Redundancy Check (CRC) to
ensure data integrity when the file is extracted from the archive.
PKARC is a FAST! archive update/create utility that generates
archives. It is completely compatible with SEAware's (Software
Enhancement Associate's) ARC program and my own FAST! archive
extraction utility PKXARC, but is many times faster than SEAware's
ARC program and faster than ANY OTHER archive utility. PKARC
achieves its speed through the use of highly optimized assembly
language code and advanced file buffering techniques. With version
1.1 of PKARC, an Enhanced Ziv-Lempel-Welch crunching technique is
employed which can result in an upto a 40% space savings over ARC.
All archives created with PKARC can be extracted with SEAware's ARC
program or PKXARC. Of course, PKXARC can extract files from an
archive many times faster than SEAware's ARC program.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 3
Using PKARC
-----------
Usage: PKARC options archive [filespec...]
Options are:
a = add files to archive d = delete files from archive
f = freshen files in archive m = move files to archive
u = update files in archive v = display verbose listing of archive
l = display software license c = add/update file comments
x = add/update archive comment
The A,F,M, and U options can be followed by a C and/or X to cause
prompting for the file comments and/or the archive comment. The V
option can be followed by a C for a verbose listing with the file
comments.
The DOS wildcards * and ? can be used when specifying file names.
Adding files to an archive
--------------------------
This option is used to add files to an existing archive, or create
a new archive with the specified files. This is the most common
use of PKARC. If no list of files is given, all the files in the
current directory will be added. Examples:
PKARC a stuff
will collect all the files in the current directory, and place them
in the archive STUFF.ARC
PKARC a a:manuals b:*.doc b:*.txt
will collect all files with an extension of .DOC or .TXT on drive B
and place them in the archive A:MANUALS.ARC.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 4
Updating files to an archive
----------------------------
This option works the same as the Add option, with the exception
that if a file already exists within an archive, it will be updated
only if the datestamp of the file on the disk is dated after the
file within the archive. This option can be used to prevent an
earlier version of a file from overwriting a later version which is
in an archive. For example:
PKARC u manuals *.doc *.txt
will collect all files with an extension of .DOC or .TXT and place
them in the archive MANUALS.ARC. If however, a file already exists
in the archive and on the disk (say STARTREK.DOC), the file
STARTREK.DOC will be added to the archive only if it is dated later
than the version already in the archive. If the file on the disk
has an earlier date, then the version in the archive will remain.
Freshening files in an archive
------------------------------
This option is used to ensure that an archive contains all the
latest versions of its files. The Freshen function works like the
Update function, except it will not cause new files to be added to
the archive. For example:
PKARC f arcutil b:*.*
will go through all the files on drive B and look for files that
are in already in the archive, but with a later date. If a later
version is found, it will be updated in the archive.
Moving files to an archive
--------------------------
This option works exactly like the Add function, except that the
original files are deleted from the disk after successful
archiving. The files are deleted only after the archive is created
and completed, and no errors have occurred. If any errors occur
during the archiving process (such as disk full) the original files
will not be deleted. For example:
PKARC m cfiles *.c
will add all files with an extension .C to the archive CFILES.ARC.
After all the files have been successfully added to the archive,
they will be deleted from the disk.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 5
Deleting files from an archive
------------------------------
This option is used to delete files from within an archive. For
example:
PKARC d games *.bas
This will delete all files with the extension .BAS from the archive
GAMES.ARC.
Verbose listing of an archive
-----------------------------
This option is used to list the contents of an archive. The
listing is in the following format:
Filename Length Method Size Ratio Date Time
-------- ------ ------ ------ ----- ---- ----
FILENAME.EXT nnnnnn aaaaaaaa nnnnnn nn% mm-dd-yy hr-mm-ss
The length is the true length of the file. The method is the data
compression technique used on the file and is one of the following:
Stored The file was Stored.
Packed The file was Packed with non-repeat packing.
crunched The file was crunched with old sytle Ziv-Lempel-Welch compression.
Crunched The file was Crunched with Dynamic Ziv-Lempel-Welch compression.
Squeezed The file was Squeezed with Huffman encoding.
The size is the resulting size of the file after compression, and
the ratio is the percentage of file space saved. For example, a
file with a length of 10,000 and a size of 2,500 would have a
savings ratio of 75%.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 6
PKARC Archive File Comments Feature
-----------------------------------
One of the unique features of PKARC is the ability to store a
comment with an archive, and optionally a comment for each file in
an archive, similar to the file descriptions found on many Bulletin
Board Systems. The archive comment is automatically displayed when
the archive is manipulated by PKARC version 1.2 or later and PKXARC
version 3.3 or later. Each file in an archive can be given a
comment which can be displayed with the verbose listing function.
Following the V option with letter C will cause the comments to be
displayed. For example:
PKARC vc utility
will display the files in the archive UTILITY.ARC with the archive
file comments in the following format:
Filename Comment Date Time
-------- -------------------------------- ---- ----
FILENAME.EXT cccccccccccccccccccccccccccccccc mm-dd-yy hr-mm-ss
The archive comment and file comments can be upto 32 characters in
length.
If the A,U,F, or M options are followed by a X, prompting will
occur for the archive comment. For example:
PKARC ax datafils *.dat
will add all files with an extension .DAT to the archive
DATAFILS.ARC and prompt for the archive comment for DATAFILS.ARC.
If the A,U,F, or M options are followed by a C, prompting will
occur for a file comment after each file is added to the archive.
For example:
PKARC ac datafils *.dat
will add all files with an extension .DAT to the archive
DATAFILS.ARC. After each file is placed into the archive, the
comment for that file can be entered.
The C and X options from above can be combined to prompt for the
archive comment and the file comments at the same time. For
example:
PKARC acx datafils *.dat
will add all files with an extension .DAT to the archive
DATAFILS.ARC and cause prompting for the archive comment and the
file comments.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 7
The C option can be used to add or update file comments. For
example:
PKARC c programs
will go through all files in the archive PROGRAMS.ARC and prompt
for a comment for each file. Comments can be updated selectively,
such as:
PKARC c programs spoolkey.sys
will allow the file comment for the specified file to be added or
changed.
The X option can be used to add or update the archive comment. For
example:
PKARC x programs
will add or update the archive comment for the archive PROGRAMS.ARC.
The C and X options from above can be combined to prompt for the
archive comment and the file comments at the same time. For
example:
PKARC cx programs
will add or update the archive comment and the file comments for
the archive PROGRAMS.ARC.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 8
NOTE: The comments are stored in a way totally transparent to
SEAware's ARC program and and have no effect on the operation
of ARC.
However, because SEAware's ARC program does not know about
archive comments or file comments, ARC truncates the comments
from an archive when modifying it. Using SEAware's ARC
program to add, update, move, freshen or delete files from an
archive will cause all comments to be lost. If you wish to
retain the comments within an archive, it is recommended that
the use of SEAware's ARC program be avoided.
Using a Ramdisk with PKARC
--------------------------
PKARC sometimes creates one or two temporary files while archiving
files. The default drive for these files is the current drive. In
order to increase performance, PKARC can be told which drive and/or
subdirectory to use for temporary files through DOS environment
strings. PKARC searches the environment for the string
PKARCTMP=pathspec. For compatibility with ARC, the string
ARCTEMP=pathspec can be used as well. For example if drive D is a
ramdisk, entering:
SET PKARCTMP=D:
at the DOS prompt will cause PKARC to use drive D for temporary
files.
Using PKARC in a batch file
---------------------------
If you are using PKARC from a batch file, you can test if PKARC
aborted with an error using the DOS errorlevel variable. PKARC
returns a non-zero errorlevel if an error occurred, and a zero
errorlevel for normal termination.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 9
PKARC Error Messages
--------------------
When any of the following errors are detected, PKARC will display
the indicated message and abort to DOS. All original files and
archives will be intact, as PKARC does not overwrite or delete
existing files on the disk until the entire archive processing has
been successfully completed.
PKARC: Unknown option: (unknown character)
The displayed option is unknown.
PKARC: Insufficient Memory
There is not enough free memory to run PKARC.
PKARC: No archive specified.
The name of the archive to be processed must be given.
PKARC: No files specified for deletion.
The delete option was specified, but no files were given.
Unlike other options, delete does not assume *.* if no specific
files are given.
PKARC: Can't find XXXXXXXX.YYY
The specified file(s) could not be found.
PKARC: No file(s) found.
No files were found to add or update to the archive.
PKARC: Can't create file XXXXXXXX.YYY
The displayed file could not be created. The output directory
is probably invalid or full.
PKARC: Too Many Files.
This error will occur if more than 512 files or 16 different
drive/pathspecs are given at one time for the add, update,
freshen, or move options.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 10
PKARC: XXXXXXXX.YYY is not an archive.
The archive name given to PKARC existed on the disk, but either
is not an archive, or is corrupted.
PKARC: Can't open XXXXXXXX.YYY

PKARC Revision History
----------------------
*** PKARC version 1.0, 8-06-86 ***
Initial release.
*** PKARC version 1.1, 9-12-86 ***
Enhanced Ziv-Lempel-Welch compression was added to PKARC. The
enchanced crunching algorithm provides superior compression ratios
over the traditional crunching algorithm used in SEAware's ARC
program. Files crunched with the enhanced crunching algorithm are
up to 40% smaller, yet still fully compatible with ARC and PKXARC.
File buffering has been drastically improved, resulting in faster
compression, especially on floppy disks.
The improved buffering and other optimizations have resulted in a
twofold increase in archiving speed over PKARC version 1.0.
*** PKARC version 1.2, 10-23-86 ***
PKARC version 1.1 inadvertently introduced a rare bug involving
squeezed files. This has been corrected in version 1.2.
Archive commenting ability has been added to PKARC. PKARC now
allows a comment to be assigned to an archive, in addition to each
file within an archive. The archive comment is automatically
displayed when the archive is manipulated by PKARC version 1.2 or
later and PKXARC version 3.3 or later.
File buffering has been improved. While PKARC will still run in
minimum of 128K of RAM, PKARC will take advantage of upto 224K of
RAM if available to increase file buffering.
The Enhanced Ziv-Lempel-Welch compression has been slightly
improved. Some files will compress upto 5% smaller than with PKARC
version 1.1. Binary files should experience the most improvement.
Optimizations in PKARC version 1.2 have resulted in upto a 20%
increase in archiving speed over PKARC version 1.1.
PKARC FAST! Archive Create/Update Utility Version 1.2 10-23-86 Page 12
General Information
-------------------
PKARC will run on any IBM PC/XT/AT/RT/jr/Portable/Convertible or
DOS compatible whatever running PC/MS-DOS 2.0 or higher with a
minimum of 128K free RAM.

PKXARC FAST! Archive Extract Utility Version 3.3 10-23-86 Page 5
PKXARC history
--------------
Soon after the archive file format was introduced into the public
domain, it became popular and many BBS files were transfered this
way. The archive format is a convenient way to put several files
into one and compress them for effecient disk storage and reduced
transfer time, in one step.
However, the archive utility was much slower at extracting files
than equivalent UnSQueeze type programs. In the inevitable quest
for faster archive file extraction, PKXARC was created.
Changes in PKXARC version 2.3
-----------------------------
The ability to extract dynamic Ziv-Lempel-Welch encoded files was
added. Version 5.0 of ARC introduced a new, more efficient
variation of Ziv-Lempel "Crunching". PKXARC can now extract files
Crunched with this method, approximately 3 times faster than ARC
5.1.
Changes in PKXARC version 2.4
-----------------------------
Performance for extracting dynamic Ziv-Lempel files has been
improved. Files which are identified as "Crunched" (with a capital
C) on the ARC verbose listing extract 15-20% faster than before.
When a "Disk full" error occurred, previous versions of PKXARC
would leave an empty or incomplete file on the disk. PKXARC now
deletes any incomplete files before aborting with a "Disk full"
error.
Changes in PKXARC version 2.5
-----------------------------
The ability to extract specific files was added. PKXARC can now be
passed the specific names of files to be extracted from an archive
on the command line.
PKXARC FAST! Archive Extract Utility Version 3.3 10-23-86 Page 6
Changes in PKXARC version 2.6
-----------------------------
Extraction performance for all compression types has been
significantly improved over PKXARC version 2.5. Files that are
crunched with older versions of ARC (pre 5.x) extract 5% faster.
Squeezed files extract 15% faster. Files that are Crunched with
ARC 5.x extract 20% faster.
Changes in PKXARC version 2.7
-----------------------------
Extraction performance of Squeezed files has been improved more
than 60%. PKXARC version 2.7 can extract a Squeezed file more than
8 times as fast as ARC 5.1.
The message displayed when a file is being extracted has been
enhanced to indicate the compression method used to store the file.
Message Meaning
------- -------
Extracting The file was Stored.
un-Packing The file was Packed with non-repeat packing.
uncrunching The file was crunched with old sytle Ziv-Lempel-Welch compression.
unCrunching The file was Crunched with Dynamic Ziv-Lempel-Welch compression.
unSqueezing The file was Squeezed with Huffman encoding.
Changes in PKXARC version 3.0
-----------------------------
The following functions have been added to PKXARC version 3.0:
Extraction of files to the console or printer.
The ability to display a verbose archive listing.
PKXARC FAST! Archive Extract Utility Version 3.3 10-23-86 Page 7
Changes in PKXARC version 3.1
-----------------------------
A minor bug in the pattern matching code for individual file
specifications when using the wildcard "*" was fixed. For example,
previous versions of PKXARC would not correctly match "flight*.com"
to the exact filename "flight.com". This has been corrected in
PKXARC version 3.1.
The verbose archive listing now displays the total number of files
in the archive.
Extraction speed has been increased 5-10% for all decompression
methods.
A "jr" version of PKXARC was created for computers with limited
memory. PKXARCjr requires only 74K of free memory to run, but is
slightly slower than the standard version for most archives. Both
versions will run on any type of computer providing there is
sufficient free memory.
Changes in PKXARC version 3.2
-----------------------------
The archive test function "/t" was added to PKXARC. This function
tests the integrity of the archive without extracting the files to
disk. Specifically, the CRC for each file is computed and compared
against the correct value stored in the archive.
Extraction speed has been increased by 5% for most files.
Changes in PKXARC version 3.3
-----------------------------
Support of the PKARC archive comment feature was added. PKXARC
will automatically display an archive comment if it is present in
an archive.
When extracting files to the printer, PKXARC will now print a
form-feed character after each file.
Extraction speed has been increased by 5% for Crunched files.
Using PKXARC in a batch file
---------------------------
If you are using PKXARC from a batch file, you can test if PKXARC
aborted with an error using the DOS errorlevel variable. PKXARC
returns a non-zero errorlevel if an error occurred, and a zero
errorlevel for normal termination.
PKXARC FAST! Archive Extract Utility Version 3.3 10-23-86 Page 8
General Information
-------------------
PKXARC will run on any IBM PC/XT/AT/RT/jr/Portable/Convertible or
DOS compatible whatever running PC/MS-DOS 2.0 or higher with a
minimum of 128K free RAM.

The BANNER program makes long, large-letter banners on your printer
from console input. All sources are presented in case you want to
customize it.
Installation:
Before use, rename either BANV1.EXE or BANV2.EXE to BANNER.EXE
so the command "BANNER" will work. Use BANV1 if you have PCDOS 1.1 or
thereabouts, BANV2 for DOS V2 or later.
BANNER produces output that is designed for 132 character wide
printers. Typically its output is a line of up to 132 ASCII characters,
a single carriage return (no linefeed), another line of up to 132 ASCII
characters, and then a carriage return/linefeed combo, for each "raster"
it uses. This allows a denser banner due to overprinting two characters.
However, due to the great variety of printers out there, BANNER makes NO
attempt to set the printer up in any way. It also doesn't mess up any
presets. Thus, for successful use on many printers you'll want to make
sure that single CR doesn't advance the paper (I believe Epson printers
work as they need to for this), that your printer is set to condensed
letters (so there'll be 132 across), and you'll probably want to set your
printer for 8 or 10 lines per inch. This means, get out the printer manual
and find out what escape and/or control sequences you need to send to
the printer and arrange to do so. (You can either create a short file
and print it, or write a short BASIC program to emit the necessary
controls.)
Use:
To use, type BANNER to activate the program.
It will first ask you for its input and output file specifications.
This will allow the program to read a disk file for input and write
one for output if desired.
Normally, for input file specifier just type
CON:
(including the colon) to signal you'll put your text in on the
console.
For output, normally just enter
LPT1:
(including the colon) to signal you want the output to go onto
the line printer. If you want it to go to LPT2:, type that, and
if you want it on disk, just give a filename. Files get large,
so be sure you have LOTS of room on disk.
Banner just does a Fortran OPEN on the file so specified.
Some terminate-and-stay-resident utilities mess up certain Fortran
OPENs, so if you have problems, try booting a clean DOS (rename
CONFIG.SYS and AUTOEXEC.BAT temporarily) and try again. Banner has
run on a number of clones and will usually be OK then. If it isn't,
sorry, something about your machine is messing Fortran up...
The program then enters a loop asking for input lines. Its
prompt looks like this:
ENTER INPUT LINE:
You type a character which may be space, +, or -, followed by
up to 78 characters of text to go onto a banner.
If your initial character is space or + sign, the letters will be
dark on white paper. If your initial character is - sign, the
letters are white on dark paper. The program uses normal text
characters to darken regions of the paper. This is seldom a
problem.
Press the Enter key to enter the text. The program will then
begin printing the banner. When it finishes it will prompt
again for an input line. You may enter several in a row if
desired.
If you enter several, they just come out serially. The
font is a variable pitch Roman font. Most of the printable
ASCII character set is included plus upper and lowercase
alphas and numbers. Some characters are however not there
so a bit of testing may be needed if you want to use lots of
special characters. No support for extended characters is here.
Character sizes can be configured only by setting spacings
in your printer, which many printers CAN do. If the single
return is a problem, you can output to a disk file and edit
the output before printing.
When you are done, type a control-Z (hold down the Ctrl key and
type Z) followed by Enter. This terminates the program. It will
be acted on when the control-Z is entered at an input prompt.
PLEA:
If you find this program useful, pass it on to your friends,
neighbors, etc. etc. and let them enjoy it.
Thanks.

Introduction to TECO Context Editor
-----------------------------------
The TECO (TExt COntext) editor is a non-visual, character oriented
editor which was developed at the Massachussets Institute of Technology in
the late 1960s as part of a project in artificial intelligence. When fully
implemented, TECO supports conditionals, branching, and forms its own unique
programming language, in fact EMACs was originally written in TECO !!! My
version is considerably simplified from full-blown TECO, but it still is
very powerful, allowing the user to edit BINARY (ie .EXE) as well as simple
ASCII files, changing the value of arbitrary bytes anywhere in the file.
To start editing in my version of TECO, you must give a file
specification on the command line. Do this by typing either
TECO myfile.ext
if you want to edit "myfile.ext", or you can type
TECO outfile.ext=infile.ext
where "outfile.ext" is the output file, and "infile.ext" is the source
file. To create a file from scratch, enter the command
TECO newfile.ext=NUL
where "newfile.ext" is the new file, and "NUL" is the null device.
Congratulations!! You are now in TECO mode, and can start using
the TECO command set. TECO commands are character sequences of the form
number letter string ESC
where "number" is signed number which defaults to 1 if not specified,
"letter" is a valid TECO command, "string" is the object for the command,
and "ESC" is the escape key (which echoes as $ on the console display).
Commands sequences are not executed immediately, but are stacked in a buffer
for later execution. All the TECO commands stored in the buffer are then
executed at once when the user types two ESC characters. The TECO commands
implemented are:
num A - Appends "number" pages of text to work area
from the input file, where a "page" is
defined as an arbitrary number of bytes,
ending in "Form Feed"
num C - Advance "number" characters in the page.
num D - Delete "number" characters.
EF - Exit TECO without writing this page to
the output file
EX - Exit TECO, writing this page out and
then copying the remainder of the input
file to the output file. Normal TECO exit
num FS old ESC new ESC - Replace string "old" with string "new"
a total of "num" times. Replace fails if
string "old" not on current page.
num FN old ESC new ESC - Replace string "old" with string "new"
a total of "num" times, Paging in text
as necessary...
HK - Delete everything in the current page.
HT - Type everything in the current page.
num I - Insert a single ascii character whose value
is "number" into the page.
I text ESC - Insert "text" from buffer.
num J - Jump to position "number" in page. If
"num" is omitted, go to start of page
num K - Kill "number" lines from the page.
num L - Advance "num" lines in page.
num N string ESC - Search for "string" a total of "num" times
Go to end of file if needed to find "string"
num P - Write page to the output file, and read in
a new page from the input file. Do this
a total of "num" times.
num R - Go backward "num" characters in the page
num S string ESC - Search for "string" a total of "num" times,
with error if not found on current page.
num T - Type out next "num" lines in page
num V - Type out "num" lines preceding and "num"
lines following current location in page.
num < string ESC > ESC - Iterate the "string" TECO command(s) within
angle brackets a total of "num" times.
If "num" not specified, iterate forever.
This is a *VERY POWERFUL* command.
^C - Exit TECO and delete output file. The
input file will be left untouched...
There are also some characters which assume numeric values. These are:
B - This is a synonym for 0 (zero)
Z - This is the number of characters in
the current page
. - This is where you are in the page.
(this version of TECO does not support arithmetic with numeric values.)
To cancel TECO typeout, hit CTRL-O, and all output will be suppressed
until the next TECO command string is requested from the console.
