MPE/iX System Utilities Reference Manual

Chapter 18  PATCH 

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.
