Re: Coding subprocedures in CL

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

I think you got confused by Rob's use of the word subprocedure and the 
command CALLSUBR.

In a single CL program there are NO subprocedures that are callable from 
within the same CLLE program.

There are subroutines since around V5R4 that you can use within CL - I 
think they are very nice for compartmentalizing code and cleaning up the 
main section, something we've not been able to do in CL before that.

See some of the other posts in this thread for more about this - 
including thoughts similar to yours - but any other CL "procedures" need 
to be in completely separate objects - I can envision a service program 
built from multiple CL *modules, somewhat following what you suggested 
here.

But those will not be called with CALLSUBR.

Cheers
Vern
