Operation
Use PATCH to access, display, and/or modify a program file's object code without recompiling the program. You can make simple changes to program instructions or to global stack area variables on compatibility mode programs. PATCH requires the memory location of the target program symbols, the beginning locations of each program unit, and the offsets for each line of code from these locations. This data may be gathered in a number of ways depending on the source language of the program. PATCH supports four subcommands (D, M, DG, and MG) to display the code segment contents, to modify the code segment contents, to display the global area of the initial stack, and to modify the global area of the initial stack. PATCH can bypass normal MPE/iX safeguards and modify the contents of privileged program files.

CAUTION: PATCH bypasses normal MPE/iX safeguards and modifies 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 that you make to the operating system or system files. For more information, contact your Hewlett-Packard service representative. |
