M4 does look like an excellent choice, as far as capabilities go. But
John's point is exactly what I was thinking: How do I run M4 against my
PDS input? If someone can point me to some JCL to accomplish this, I will
probably head in that direction.
The next closest option looks like the C preprocessor. The PPONLY option
causes the preprocessed code to be sent to SYS010 without invoking the
compiler. I've run some experiments, and the only shortcoming seems to be
that all macro expansions result in a single line of output. (A
requirement I failed to mention.)
Multi-line macro definitions, which all but the last line ending in a
backslash, always seem to create one long line. This macro definition:
#define PAT3 \
* This is a \
multi-line \
macro expansion
generates this output:
* This is a multi-line macro expansion
My solution to this is to include my own delimiter in the macro definition
and use a Rexx post-processor to line-break at the delimiter.
I will continue to appreciate suggestions.
