If you can call a CL passing parameters, you can call Python with those
params, because you can call Python from a CL.

A little while ago, I had to plug in a Python function/process into an
existing RPG program. I'm on 7.3, and to the best of my knowledge,
Python is not a participant in the CALL/PARM family. That is, if my RPG
program were to call a CL which were to invoke a Python program, and the
Python program were to want to return a mixed case name back to the
caller, there's no mechanism to pass it back in the parameter list.

I solved it thanks to Scott Klement's insights into how pipes work
between PASE and ILE. Basically, my RPG program sets up pipes for the 3
'standard' streams, does a spawn() that invokes the Python program with
UPPER_NAME_PARM and then Python does its thing, putting lower_name_parm
on STDOUT, which the RPG program then does an fdopen() and fgets() to
retrieve. Don't forget to translate from ASCII :-)

If there's a simpler way that a CLP can get an answer back from a Python
program, I'm all ears!
