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
|
ENDIF
