A fine collection of tools for communications users and others.  The
SQIBM and USQIBM programs compress and expand files to save on costs
when using modem transmission.  TALK450 shows how to add 450 baud
capacity to your Hayes 300 modem.  There are other goodies like
SCRNSAVE, which prevents phosphor burn on your monitor, and a series of
batch files to give sorted directory listings.

How to Start: To run a COM or BAT program simply type its name and
press <ENTER>.  To read DOC files simply enter TYPE filename.ext and
press <ENTER>.

	The batch files DN.BAT, DX.BAT, DS.BAT and DD.BAT write
sorted directories on the screen only. They sort on the directory
line starting with fileName, eXtension, Size or Date (mm/dd/yy).
The sorted directory can be stored by modifying the batch files,
as in the example of DXSAVE.BAT.
	These batch files have two dummy parameters: drive and
filename and extension restriction, if any. Thus, to sort the files
on drive E that satisfy the filename and extension restriction of
ABC?.*, sorting by size, one uses:
		DS E ABC?.*
The spaces between S, E and A are important.
	Note that if one sorts on a restricted set of files, such as
with DX E *.COM, then that amounts to the same thing as DS E *.COM.


SCROLLK:  This machine-language program is attached to DOS
whenever you run scrollk.com with the A> prompt showing. It
allows much better scroll control than <Ctrl-NumLock>. See
John Socha's article in Softalk for the IBM Personal Computer
for May 1983 for more information. Scrollk will be handy in
using files under Directory 4: "Quick Looks at Distant BBSs".



SQ.COM -

The purpose of this program is to squeeze all types of files. It is
most effective on text files and least effective on binary files such
as .EXE and .COM.

The output file name is changed so that the middle letter in the
filetype is changed to a "Q". For example, a file called  ABC.TXT
would be called  ABC.TQT. The input file is not changed.

To run the squeezer:

SQ filename.filetype               (i.e.  SQ  ABC.TXT)

There are no messages displayed while the program is running. Make sure
you have enough disk space to handle the output file (which can be 5% to
50% smaller than the original depending on the type of file).


USQ.COM -

The purpose of this program is to un-squeeze processed by  the SQ.COM
program. This program will recontruct the files to their original state
before compression.

You must specify the input and output files names (if missing, you
will be prompted for them).

To run the un-squeezer:

USQ d:filename.filetype d:newfilename.filetype   (i.e.  SQ  ABC.TQT ABC.TXT)

After specifying the file names, you will be asked if this is a text file.
Reply as appropriate. The replies are Y or N.

Make sure you have enough disk space to handle the output file which could
be up to twice the size of the input file.
