So if EOS is announced - the most that means is no new fixes for that version of
the Compiler. I do not think the compiler shuts itself down. You can still use
it.
Note: I think IBM has altered the pricing on V3/V4 Enterprise Cobol Compiler to
be the same as V5 Enterprise Cobol compiler. I am not sure if there was a cost
increase from V5 to V6 Enterprise Cobol Compiler. So if cost is a factor, I
think that has already been handled by IBM.
Depending on what your requirements are, here are some things to look at for an
upgrade
1) Do you have a source management tool that needs to be altered for the new
compiler? (Change Man, Endevor, CA Telon, etc...)
a) New work would use the new compiler
b) old work may use the older compiler
2) What are the new Reserve words in the Compiler and are any current programs
using them?
3) What COBOL options are in place today, and how does the new compiler alter
that environment
a) In a previous release PMAP is LIST on the compiler options
3) Are the benefits of the new Compiler worth the effort to upgrade? (Most have
indicated yes)
4) Do you have very complex Programs that need TLC to upgrade? These could be
including, CICS, IMS, MQ, DB2 type of programs
5) How long does your company require for a checkout for the new compiler?
a) Some shops have mandatory recompile Everything under the new compiler
b) Some shops have compile the worst case programs as a test case of the
new compiler
c) Some shops have performance requirements for a new compiler. Program
must run the same way or better. Not worse
6) Will you need to run only new work through the V5/V6 Enterprise Cobol
compiler while old work gets the current compiler?
a) This may be needed as the older programs have to be evaluated and
that takes time.
7) How long will this process take. As other have pointed out - the BIG CLOCK
Starts the minute you being this process. Work with your IBM Representative on
actual requirements.
8) Older programs running do not necessarily need to be recompiled. That is
why the new Parmlib member was created. To allow everything to run as is.
a) When a program gets a fix - then the company should look are the
recompile with the new compiler.
There may be other considerations.
To upgrade the compiler is easy. Running parallel processes to ensure
everything is working the same or better is what takes time. And what
application group is not busy and has the time to do the checkouts? Answer -
very few.
And because the LOAD lib for the compile MUST be a PDS/E, that has had a new
level to a simple roll out.
I hope this helps
