for loop behavior

Try the following and see how it performs for you.  If you get the same
results as I did, the first loop will run for 1 iteration while the rest
will run for 5.  It's probably well documented, but I just didn't see it.

 H  dftactgrp(*no) actgrp(*caller)                       
 H OPTION( *SrcStmt: *NoDebugIO)
