RE: Need help to convert a name in upper case, to mixed case

That got me thinking about the UNIXCMD library. How about this?

RPGLE:
Dcl-f UNIX disk(1024) handler('UNIXCMD/UNIXCMDOA' :UnixCmd) usrOpn ;

Dcl-s UnixCmd char(1024) ;
Dcl-ds StdOut len(1024) End-ds ;

Dcl-s Display char(52) ;

//----------------------------------------------------------------------

UnixCmd = '/QOpenSys/pkgs/bin/python3 src/Python3/misc/proper_case.py "GEORGE" "WASHINGTON"';

sysCmd('ADDLIBLE UNIXCMD *LAST');
Open UNIX;
Read UNIX StdOut;
Dow not %eof(UNIX);
Read UNIX StdOut;
Enddo;
Close UNIX;
sysCmd('RMVLIBLE UNIXCMD');
Display = StdOut;
Dsply Display;

*inLR = *on;
Return;

Python:
import sys

parms = sys.argv
parms.pop(0)

return_value = ""
try:
for parm in parms:
return_value += parm.capitalize() + " "
except:
return_value = "Error"

print(return_value.rstrip())

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!
