would enter: MR T'S SUPPORT* . This
rule applies whenever you search even
if you know the exact file name you
must add a "*" as the last character.
If you select (5) from the first menu
you will then see the second menu. If
you select (1) printing will start as
soon as you enter 1. Any key will halt
it and then any key wil resume it. If
you enter "Q" that will quit this mode.
This same group of rules applies to any
area of the program where you are
printing or have selected a screen
display in lieu of printing.
Here are some ideas you may wish to
use. I only log games that can be
transfered to a disk and the file names
are all visable and in UPPER CASE with
no graphic symbols. This program uses
"seq" files so searches can take some
time. Because of this I don't log all
my disks. Maybe just the 10 or 20 disk
that you normal use on a normal
basis. I found manny duplications so I
scratched a number of files. Manny
games and programs became obsolete in
this process. If this program is used
properly you should be able to locate
any file, avoid the use of the same ID
number on two different disks,print
your directories (sorted) and maxamize
disk space.

What Makes ARC Tick?
The following psuedo-code should make it fairly clear
as to what ARC is doing when creating or extracting an
archive. We get alot of questions along these lines.
Hopefully this section will answer some of them.
But first we'll define some of the terminology we will
be using.
The general format for the ARC command is:
ARC/XY/Z D:ARCNAME D:PARM1 D:PARM2 .....
The command line is the command that you typed in to
get ARC going. It is simply a series of character strings
separated by spaces. The first character string on the
command line, ARC/XY, is of course the command. X and Y are
called switches. We'll call X switch one, Y switch two, and
Z switch 3.
The remaining strings on the command line are called
parameters. Thus D:ARCHNAME is parameter number one, D:PARM1
is parameter number two and so on. ARC allows for a maximum
of ten parameters (0-9) including the command itself, which
is parameter number zero.
Note that spaces are not allowed within a parameter, as
ARC will interpret this as being two separate parameters. If
you want to specify a file named "ONE TWO THREE", then you
can do one of two things. You could specify it using
wildcards as "ONE?TWO?THREE", or you could use shifted
spaces instead of spaces in the filename; ARC will change
them to spaces and get the correct file.

When you hit RETURN, ARC does the following:
GET switch 1
TEST switch 1 for valid character... A,C,F,L,P or V
IF switch 1 is invalid then abort.
GET parameter 1
IF no parameter 1 THEN
abort.
ELSE
add .arc extension to parameter 1 if req'd
IF switch 1 is A or C THEN
open archive for write
ELSE
open archive for read
