There is a degree of binding that happens.  For example, if you do not 
supply *SRVPGM objects for all of the required imported symbols used by 
your program the program will not bind and the CRTPGM command will error 
out.

What I meant is that typically the CM process is running the CRTPGM and 
CRTSRVPGM commands, not CRTRPGMOD etc...  The former commands are binding 
together modules and resolving symbols to external *SRVPGM objects.  This 
process runs reasonably quickly.  CRTRPGMOD would be recompiling the 
source to a *MODULE (which is completely unnecessary).

I guess the problem would be if you are using CRTBNDRPG with a BNDDIR to 
reference service programs.  In this case, you would be incurring a lot of 
unnecessary compiling in addition to the binding step.
