:CATALOG:General Information on Cataloging system
This document describes a system for cataloging all of a users
CP/M diskettes. Written by Ward Christensen.
The master cataloging system consists of the following:
MAST.CAT The catalog itself
FMAP.COM Used to create NAMES.SUB, the
"transaction file" for catalog update
CAT.COM Like DIR, i.e. the lookup program
CAT2.COM Quick kludge program, lists entire
catalog, printing each filename only
once, & stringing disk names out after.
UCAT.COM The update program, merges NAMES.SUB
into MAST.CAT
UCAT.COM It now catalogs the "volume serial"
(-name.nnn).
:CATALOG:Format of MAST.CAT file
The format of MAST.CAT is:
First, a list of names of files not to be cataloged, in
parentheses. The list supplied with the sample is:
(ASM.COM
DDT.COM
LOAD.COM
PIP.COM
SID.COM
STAT.COM
SUB.COM <-- I renamed SUBMIT on most disks
SUBMIT.COM)
Then a list of all cataloged files, in the form:
filename.type diskname.serial
For example: ALLOC.COM SYSRES.802
:CATALOG:Volume identifiers
A disk must have a special filename on it, which is the
volume indentifier: -diskname.serial, such as "-SYSRES.801".
This may be done via:
save 0 b:-sysres.801 (FOR CP/M SYSTEMS)
save b:-sysres.801 1 (FOR CDOS SYSTEMS)
NOTE that the SAP (sort and pack directory) program
previously distributed by the CP/M U.G. deletes all 0-length
file entries, so if you use this utility, do a save 1, not a
save 0.
:CATALOG:Updating Process
To update the catalog for a disk, use FMAP to create
the NAMES.SUB file (which contains a sorted listing of the
files on the particular disk). Filename $$$.SUB is
automatically skipped, as I recall.
FMAP B: Q
will write NAMES.SUB to the logged in disk. Then type
UCAT which will merge NAMES.SUB with MAST.CAT, and erase
NAMES.SUB.
Note that UCAT is a "belts and suspenders" type
program, i. e. it creates NEW.CAT, and merges NAMES.SUB with
MAST.CAT and puts it there. It then does:
era mast.bak
ren mast.bak=mast.cat
ren mast.cat=new.cat
This means that unless you era mast.bak, there will be
3 copies of the master catalog on the disk during the ucat
execution. If you don't have sufficient space for it, era
mast.bak first.
:CATALOG:Retreving data from catalog
CAT works just like DIR, i.e. "*" and "?" are allowed.
However, it takes a second operand (after the filename/type)
which is the disk information, in the form NAME.SERIAL -
without the dash. Sample queries:
CAT <-- ALL FILES
CAT *.* WORK.* <-- ALL FILES ON ANY "WORK" DISK
CAT *.ASM <-- ALL .ASM FILES
CAT *.* *.8* <-- ALL FILES ON DISKS WITH SERIAL
NUMBERS 8xx
Note that the "-diskname.serial" file is written to the
disk (it wasn't under the earlier UCAT in the CP/M users
group). Thus you can get a list of all disk serials via:
CAT -*.*
but other than this one file entry, the "-" characters
are eliminated from the directory, i.e. the disk names are
stored as 7 characters (or less).
:CATALOG:Special Features of FMAP
FMAP has some additional options:
FMAP
displays a sorted listing on the console
FMAP specs
displays a selective listing. Specs mean *.asm, etc just
like DIR.
FMAP specs D
writes the names to NAMES.SUB with $1 $2 before the name,
and $3 after:
$1 $2FOO.COM $3
Thus $1 may be substituted with a command name, $2 with
a disk name, and $3 if the program takes options (only
my programs do, as far as I know)
FMAP specs Q
writes the sorted names, without any "$", to NAMES.SUB.
FMAP specs M
writes the names to NAMES.SUB with $1 $2 $3 before the name,
and $4 after:
$1 $2 $3FOO.COM $4
This is specifically for use with the modem program. For
example, to send all .ASM files from the B: disk to another
person:
FMAP B: M <-- MAKE NAMES.SUB
MODEM SO.600 NAMES.SUB <-- SEND THEM NAMES.SUB
SUBMIT NAMES MODEM SO.600 B: <-- SUBMIT THE SEND
MODEM gets substituted for $1, SO.600 for $2, and B: for $3.
FMAP specs UNN
creates CP/M users group catalog volume "nn". Not generally
useful, but thought you might like to know how it was done.
NOTE that I have found the FIND program (also
distributed on this users group disk) to be very useful when
used with MAST.CAT - suppose you have the following in
MAST.CAT:
BIOS1.ASM
BVIOS.ASM
CBIOS.ASM
M2BIOS.ASM
It's ovbious that CAT cannot find all your BIOS related files -
but if you type:
FIND MAST.CAT IOS
You will find them all
