RE: isprint() and isgraph() in RPG

I had no trouble finding the defs in QSYSINC/H(CTYPE). However, they
are all macros or inline functions. I don't see any reference to
calling an actual function in a service program.

Am I missing something?

Not sure, Scott, I don't see how you could unless you're skipping the
#ifndef __cplusplus_nomacro__ section. On the VRM540 system I'm
looking at, they're referenced toward the top, in lines 0000.36 to
0000.48. Lines look like:

int isprint ( int );

HTH. Or, what am *I* missing? :}
