COBOL prelink?
Mark Pace
VSE in the past.
What is the prelink - EDCPRLK -?
I'm used to compile and linkedit, I don't understand the purpose of the
prelink step.

Prelink is necessary to condense "long external names" (i.e., > 8
characters) into 8 characters for linking into a PDS (regular
"loadlib"). PDS load modules must have external names of 8 or less.
For COBOL I *think* this is only necessary if you use the OO features
(Object-Oriented) and communicate with Java or C++ which have long
names. For normal COBOL it is not needed.
In z/OS it is only needed for linking into a PDS. For linking into a
"program object", you can do that directly from the binder (to PDSE or
to Unix System Services directory).
For CICS and DB2 though, there is also a pre-compile "translator" step,
which IIRC VSE had as well (except in VSE it is DL1 instead of DB2,
isn't it?).

Not any more. For some time now the program binder has included
all the prelink functions. The only one that may remain is if
you want to store a DLL with a long / case-sensitive name in a
PDS instead of a PDSE or HFS directory.

A couple of really helpful courses in this environment, I believe, would
be our "Enterprise COBOL Update I: Essentials" (2 days) and our "Secrets
of Inter-Language Communication in z/OS" (3.5 days). For more details,
check out:
http://www.trainersfriend.com/COBOL_Courses/d704descr.htm
and
http://www.trainersfriend.com/Language_Environment_courses/m520descr.htm
respectively.

I believe "pre-link" is exclusive to C/C++.

VSE does both DB2 and DL1. And I'm not sure how much DL1 is left in the
world.
