Try compiling with DFTACTGRP(*NO) ACTGRP(*CALLER). That will at least remove 
the added overhead of creating an activation group each time you call the 
subprogram. A word of warning though: Don't use ACTGRP(*CALLER) if you're 
executing the program by calling it from an OPM program and using bound calls. 
Results will be "unpredictable". If you need activation groups, specify a named 
activation group. Do NOT use the default, which creates a new activation group 
each time you call the program, and can leave the old ones lying about. You 
could also look at the debug information you're keeping in the program (DBGVIEW 
- check the docs). I'd recommend using *SOURCE or *COPY, since that does not 
store the complete source member in the program object. Also, OPTIMIZE(*BASIC) 
may help some, with minimal risk of dysfunction.

What extra overhead are you speaking of with CALLB? All you really need to do 
is add the 'B'. If you build a binding directory and have a naming convention, 
compiles are every bit as easy as PDM option 14 (I named mine CP for compile).
