TOMCAT
Demo Version 0.6
Copyright Roger Clare 1986
Permission is hereby granted to copy and distribute this
Demo Version provided that no modifications are made and
that no charge is made, and that this documentation is
distributed with the program.
INTRODUCTION
TOMCAT is a disk cataloging program. It has several
good features, some of which are unusual and perhaps unique.
Fast screens.
Fast searches.
Finds and catalogs files contained within ARC files.
Catalog may be sorted by Volume or by File Name, and
all features work without re-sorting.
Index of Volumes shows empty space on each disk, and
also the date when it was cataloged.
This Demo Version is limited to a catalog of 120 volumes
or 700 file entries, which may be sufficient for many users.
The full version (Version 1.5) will handle as many entries
as available memory will allow.
|Version .4 changes
| Reading the catalog from disk into memory is now more
|than twice as fast as previous versions.
|Version .5 changes
| When scanning file names of descriptions for a string, the scan
|results may be scrolled up or down, the same as when browsing the
|catalog.
| The list of volumes may be printed.
|Version .6 changes
| Bug fix for file delete on directory display not working unless
|a full screen of files was being displayed.
STARTING THE PROGRAM
When you run TOMCAT.COM, it will look for a
configuration file (TOMCAT.CFG) in the same directory. If a
configuration file is not found, TOMCAT will create one, and
also an empty catalog file (TOMCAT.CAT). If TOMCAT.CFG is
present, TOMCAT will read it to determine the path and name
of the catalog file. TOMCAT will then read in the catalog
file and display the main menu.
MAIN MENU
The main menu shows TOMCAT's single-letter commands, grouped
by related functions.
R) Read Catalog -
This command reads the catalog file indicated by the
configuration table in memory. If a catalog exists in
memory, it will be overwritten and lost.
S) Save Catalog -
This command saves the catalog residing in memory by
writing it to the catalog file indicated in the
configuration table. An existing catalog file of the same
path/name will be overwritten.
I) Display Directory -
Displays the directory of the disk on the Input drive.
The user can delete a file from the disk directory being
displayed by hitting the 'D' key and then giving the name
of the file.
While displaying the directory, you can delete a file by
using the 'D' option on this sub-menu. TOMCAT will ask
for the name of the file to delete, and will ask for
confirmation before deleting.
L) Label Disk -
Writes a volume label on the disk on the Input drive.
U) Update Catalog -
Reads the directory of the disk on the Input drive, and
adds or changes catalog entries. If the disk is already in
the catalog, existing entries will be updated for size and
date, new entries will be added, and entries in the catalog
no longer on the disk will be deleted from the catalog. The
description of the file may be changed or entered at this
time.
W) Show Volumes in Catalog -
Displays disk volumes contained in catalog. Shows the
date each disk was cataloged, and the free space remaining
on each disk at that time.
This display may be sorted into volume label sequence,
or in order of remaining space on the volume, by using the
L or S options on this sub-menu.
T) Print List of Volumes -
Sets printer to condensed print mode and 88 lines per page.
Prints volume list in same format as display above.
E) Erase Volume from Catalog -
Removes a volume and all its file entries from the
catalog. The sub-menu permits you to display volumes as
above before entering the label of the volume to be deleted.
N) Sort by File Name -
V) Sort by Volume -
The catalog may be sorted either by File Name or by
Volume Label. The catalog may be saved (written to disk) in
either sequence, and the Search and Browse commands will
function with either sequence.
F) Search for string in File Names -
D) Search for string in Descriptions -
Searches for the given string within File Names or
Descriptions and displays all entries in which the string is
found. (See note)
P) Print Catalog -
Sets the printer to condensed print mode and 88 lines per
page; prints the entire catalog in same format as displayed
on the screen, except that both the ARC file (if any) and the
description will be shown.
B) Browse Catalog -
Moves forward and backward through the catalog using
the Up- and Down-Arrow keys to scroll, the PageUp or
PageDown keys to move by pages, or Home and End keys to go
to the beginning or end of the catalog. (See note)
NOTE: In the catalog displays, files which are contained
within ARC files are indicated by a letter "a" following the
size column. By hitting the "A" key, the ARC file in which
the file is contained will be shown in the description area.
C) Change Configuration -
The Input Drive parameter determines from which drive
TOMCAT will read the directory to add to the catalog, to
display the directory, or to change or add the volume label.
The Catalog Path/Name parameter allows you to keep the
catalog in the directory of your choice, and use a file name
of your choice.
These configuration changes affect the current session
only, unless you save the changes to the configuration file
by answering "Y" to the prompt "Save to Configuration
File?". If you save the changes, they will be loaded the
next time you run TOMCAT. Note that if you move TOMCAT to
another disk or sub-directory, you should move TOMCAT.CFG
also, unless you wish to set up a new configuration.
(Note: The following paragraph applies to Version 1.6 only.)
The Number of Volumes parameter allows you to reserve
space in the catalog for up to 2500 volume entries. The
remainder of available memeory will be allocated for file
entries. This enables you to make the catalog storage
allocation a little more efficient. For example, if you
have many volumes with only one or two large files on each,
you may increase this parameter. This parameter defaults
to 120 volumes. Note that changing this parameter has no
immediate effect on the catalog, as space is allocated at
the start of the program. The changed Configuration File
must be saved, and the new parameter takes effect when the
program is next run.
X) Exit -
Exit from TOMCAT. If the catalog has been changed in
memory, a warning message will be displayed, asking if you
wish to write the updated catalog to the catalog file on
disk.
FOR BIGGER CATALOGS
If you like the features of TOMCAT, but have more disks
or files than this Demo Version can handle, you can purchase
Version 1.6 for only $20. Order from:
