Additional Discussion
The PATCH utility accesses, displays, and/or modifies a compiled, prepped executable modules. You may make simple changes to program instructions or to global stack area variables with this utility. You may use PATCH on compatibility mode programs only.

Before using this utility you should be familiar with machine-executable instructions and the internal format of executable modules in the HP3000 system environment.

CAUTION: PATCH bypasses normal MPE/iX safeguards and will modify the contents of privileged program files. It is therefore possible to corrupt system file(s) or the entire operating system. Hewlett-Packard is not responsible for modifications you make to the operating system or system files. For more information contact your Hewlett-Packard service representative.
