Doesn't the example in the benchmark show performance problems in EXECIO
instead of REXX? EXECIO, IMO, is not part of the REXX interpreter, but
instead
it is a vehicle (an external function) to do I/O from REXX on z/OS.
Other REXX implementations
(for example, on Linux or Windows) don't use EXECIO etc.; I/O there is
done with
native REXX functions.
So to be fair, the REXX interpreter functions should be compared with Lua
interpreter functions, for example: some loop control or arithmetic.
Compiled languages like C will always outperform interpreted languages
in this area, so such comparisons are only of academic interest.
Kind regards

Good one Dave, glad you were able to convince your "powers that be" to get this
out the door.
Let's hope it gets some acceptance.
Now you have Lua installed why don't you bench-test it against REXX and
report if you get similar results to what I get on my machine
Now don't you go training everybody out there as to what a slug REXX really is
... ;-)
