Re: COBOL/ILE questions

["Jim Essinger" <dilbernator@xxxxxxxxx>]

Michael,

How about "It depends"?

ILE programs, if designed and created correctly, can be fast, with little
overhead on the call.

Does the utility program get called many times from the same programs,
before they end?  Do they get called once from a lot of different programs?


CL and COBOL, (and yes gasp RPG) all have ILE capabilities.  Some system
stuff I have done in ILE CL and application in ILE COBOL.  Jon Paris and
Susan Ganter are great resources for learning ILE.  They teach/have taught
classes about it.  You have already heard from Jon on this and the WDSC
list.

COMMON would also be a good education source to learn system i type things,
although COBOL is VERY light in sessions.  ILE concepts taught for RPG
apply, even though some of the examples have to be translated to COBOL.
