DOS PATCH UTILITY Version 1.20
PATCH.COM is a utility intended to make disk based patches to DOS files. PATCH
patches the files at an absolute offset in the file, or is capable of adding to
the end of the file. The maximum size the file to be patched can be is 64K
Syntax for the command is as follows:
PATCH [d:][path]filename.ext [d:][path]
where the first string is the name of the file containing the patches and the
second string is a path pointing to a directory containing the files to be
patched. For example:
PATCH C:\PATCHES\DOS20 A:\
would look in the \PATCHES subdirectory for the file DOS20. This file should
contain the patches. PATCH would then look for the files to be patched in the
root directory of the A: drive.
PATCH will default to the current drive and current directory if a path and a
drive letter are not specified. For example, for a user to install a patch to a
DOS disk, the easiest way to install the patches would be to copy PATCH and the
file containing the patches into the directory containing the files to be
patched. Then by making this directory the current directory on the current
drive, the patch could be made by simply going PATCH filename.ext. For example,
using the patch file DOS20 the intall procedure would be:
PATCH DOS20
This would patch files in the current directory of the current drive. By using
the defaults, it becomes much simplier. As typically the DOS files will be in
the root directory of a diskette, installing the patches should be an easy
process. Note that PATCH does not work on write protected diskettes. If a user
wishes to patch DOS files, he should make a non write protected copy and then
patch the copy.
To distribute PATCH, a user should be given a copy of PATCH.COM, the appropriate
patch file, and a list of what files are patched and the problems fixed.
