->>> Compare Catalogs <<<-
9 Nov 85
CCAT is a "double-ended" list comparison program intended
specifically to be used as a companion to the excellent MCAT and
XCAT programs by Irvin M. Hoff. CCAT was written to provide a
convenient means by which to compare the catalog listings of two
independent collections of programs (e.g., the catalog listing of
a working library and that of an archive collection). Inputs to
CCAT are MAST.LST files generated as output by the XCAT listing
program. The output of CCAT is a double listing:
(1) A list of all files in MAST.LST A
which do not appear in MAST.LST B
and:
(2) A list of all files in MAST.LST B
which do not appear in MAST.LST A
The output from CCAT may be directed to the printer or to a disk
file, but is always sent to the screen. If a disk file is selected,
a backup of a previous CCAT output file is automatically created.
An example of syntax for CCAT when input data is put on the
command line is:
A>CCAT B:MAST.LST C:MAST.LST
If only CCAT is entered on the command line, the remaining data
is requested. The request for an output file name may be
answered with a carriage return if the default name is acceptable.
The two input files (any name), may be selected from any drive.
File output will default to the logged drive as ODDFILE.LST
unless otherwise specified.
CCAT consists of a COM file and CCAT.000 (an overlay). The overlay
allows very large (more than 3000) MAST.LSTings to be processed
and the output to be neatly formatted. The Turbo Pascal source
file is included.
NOTES: If user wishes to rename CCATxx.COM, the source file
must be recompiled - otherwise the overlay will not be found
at run-time. A run-time error (F0) will be indicated.
CCAT must be run from the logged drive. (The program
expects the to find the overlay on the logged drive during
execution.)
