Overview:
ZSView is a dedicated viewer for the file listings contained in
ALLFILE.DIR. ZSView will also handle the individual directories in
ALLFILES.ZIP as a whole, as if they were all contained in ALLFILE.DIR,
creating an index for all 97 directories. ZSView will handle any
individual directory up to about 2 Meg.
ZSView can also sort the file listings in a directory by Name,
Date or Size. And ZSView can handle the multiline file descriptions
up to 50 lines per listing.
ZSView is written in QB 4.0, so it will run on an XT (although
the sorting routines may be quite slooow on large directories).
Also included in the package is PRETREAT. This program is
run once before using either ZSView or ZS. PRETREAT corrects
problems in ALLFILE.DIR or the file directories which would cause
trouble for the search and sort routines in ZSView or ZS.
- 2 - ZSView.DOC
Before you begin:
If this is the first time you are running ZSView (or ZS)
then you must run PRETREAT.EXE before you run ZSView (or ZS).
PRETREAT corrects four problems in ALLFILE.DIR or the file
directories by use of these three options:
PRETREAT T X F
Options: T - Tabs are converted to 7 spaces. (Although in
the latest ALLFILE.DIR {4-2-96} there were
no tabs used.)
X - Useless lines with "@X80" contaminating the
filename area are removed.
Simultaneously, any lines longer than 80
characters are shortened to contain only
the first 80.
F - That portion of the DIR98 listing in
ALLFILE.DIR (between the two
=================== lines) which doesn't obey
the rule whereby multiline descriptions are
marked off with a vertical bar, "|", is
changed to comply. (This is not necessary
for the files in ALLFILES.ZIP -- no DIR98!.)
The few blank lines left and the two
=================== lines cause an
inconsequential problem when the file is
sorted: they all appear at the top or bottom
depending upon the type of sort done.
The options for PRETREAT may be run together or individually
as circumstances dictate.

ZSView:
ZSView is written in QB 4.0 and runs in glorious 16 color 80 x 25
text mode. ZS can be either in the directory with the files being
searched or on the path.
Usage:
ZSView
That's it! No options are needed. ZSView will scan the current
directory to determine which set of directories is being viewed.
ZSView first looks for a file called ALLFILE.DIR. When that's found,
ZSView then looks for the associated index file, ALLFILE.IDX. If
this is the first time you're running ZSView (or if you've had to
delete the index previously) then an index file will be created.
Once that's done without error, you'll be placed into the Main Index,
the table of contents for ALLFILE.DIR.
If the hard drive directory you're in doesn't contain ALLFILE.DIR,
then ZSView will look for a file called DIR01. If found, ZSView
assumes you are viewing the individual directories and then looks for
the associated index file ALLFILES.IDX. If the index file isn't
found, ZSView will create it and then launch you into the Main Index.
If neither ALLFILE.DIR or DIR01 is found, you will be dumped back
to the DOS prompt with an error message about not being able to find
any files to view. If you were trying to view the individual
directories contained in ALLFILES.ZIP and were simply missing DIR01,
then after you restore DIR01 you should delete ALLFILES.IDX and rerun
ZSView to recreate a new index.
Options:
Actually, there is an option you can use. If you wish ZSView to
start up in a specific directory, then include that number on the
command line:
ZSView ##
and ZSView will launch you into that directory for immediate viewing.

Main Index:
When ZSView begins (assuming the IDX file exists) it will place
you into the Main Index. This is a table of contents for the
directories contained in ALLFILE.DIR or the individual directories
originally packed in ALLFILES.ZIP.
A reverse video highlight bar will tell you which directory is
currently under consideration. Hitting "Enter" will allow you to
view the contents of that directory.
