MATCH -- Version of 1/31/91
Match is a program to compare two text files and report the differences. The executable
file contains versions for both DOS and Windows. Use of the Windows version is
documented in the Help file. The DOS version can be invoked from the DOS prompt
via the command line
match <left file> <right file>
It's output will show the differences between the files in terms of added and changed
blocks of lines. This differs somewhat from the Windows output, which shows the entire
file with reverse video for the differences. The DOS version output is setup for a
132-column printer, and may truncate lines when they are too long to fit the output format.
The DOS version is code I've run for quite some time; the Windows version uses the same
comparison "engine", but contains mainly new code (and has the usual new software bugs).
The following notes apply to the Windows version:
1. For the present version, every line causes allocation of a new memory block (Yeah,
gag, I know. Fixed in the next version). Since Windows imposes a system-wide
limit of 4/8K handles, the size of files you can compare is limited, probably to about
1 or 3K lines. (Standard mode is 4K handles, others 8K I think).
2. Certain situations seem to cause the last line or so of files to not be displayed.
3. The horizontal scroll bars don't do anything yet.
