Implementing relative instructions into your macro's won't buy you much. In fact, you can
skip this step until you make your programs optimized to using relative instruction by
including "COPY IEABRC" at the beginning of the program will change offset
branches into relative branches without modifying anything else.
On z/OS 1.10 and higher, you might consider using IEABRCX instead. Example:
IEABRCX DEFINE Define B-to-J conversion macros
IEABRCX DISABLE (same)
Then you can easily enable/disable only where needed. Example:
IEABRCX ENABLE Enable B-to-J conversion
IKJRLSA POPTANSP Release IKJPARS storage
IEABRCX DISABLE Disable B-to-J conversion
IEABRCX also supports PUSH/POP so you can easily enable/disable the
conversion in a macro without having to know what's going on in the open
code.
None of this works on z/VSE. :-( It's one reason why we do our z/VSE
product assemblies on z/OS.
