All I can offer is some anecdotal evidence. I tried using CL for format
selector programs once. A format selector is like a trigger that doesn't do
anything but receive the buffer, set an internal code value and exit. I was
horrified to find that in addition to initializing and freeing automatic
storage for every record, it was writing a message to the joblog that said
it was terminating because it had reached the end of its code. I don't have
any timings, but the overhead was prohibitive, and moving to RPG fixed the
problem.
