RE: Command Creation (Was: Recursive CL - Data decimal error)

My 'default" is to name the program to call the same as the command i.e.
WRKCUST command calls CL program WRKCUST to work with customers....

:I believe there is a reason command creation is underutilized

:
:I create an RPG program, very simple to compile.  14 using
:PDM. I create CL program, 14 using PDM. I create DDS, 14 using
:PDM. I create command source.  14.  Remember to prompt, now what is the
:   call I want to use?  And going back having to recreate commands
:   months later, what program was this command supposed to call?
:   No idea.  I hope they documented it in the command source
:   (yeah, right, like that'll ever happen).
:
:I think commands would be utilized a lot more if you could
:actually specify the program to call inside the command source
:itself, then just compile with 14.
:
:Anyway, that's why *I* don't utilize them that much.
