Is there any performance benefit to compiling a REXX EXEC if it will be
EXECLOAD'd for the lifetime of it's use?
For example, I have a service machine which, upon startup, EXECLOADs
some EXECs it needs over and over. It/they remain EXECLOADd until the
service machine is shutdown. The EXEC is
EXECLOAD simply loads it, so it saves on I/O, no more no less, no
tokenization like what happens on OS/2.
Compliling will save CPU cycles, but the compiled exec is larger, hence
EXECLOAD of a compiled exec is even more recommended.

Oh yes! EXECLOAD simply loads a file into storage. If you display
memory, you'll see the source (compiled or non-compiled data directly
from your file) ... and that's what is interpreted when you run the
non-compiled EXEC or run directly from a compiled EXEC.
