Curiosity/Impact questions
PROGxx has existed for almost 25 years, and support within there for
dynamic LNKLST for almost 20 years.
We're looking at some new work for which we likely won't change the
LNKLSTxx path, thus requiring use of PROGxx for defining the LNKLST in
order to use the new functionality.
So,
-- are folks still using LNKLSTxx
-- why? (this could include lack of need to change)
-- if you are using it, do you have concerns with changing?
-- are you aware of the CSVLNKPR exec (in samplib) that exists to create a
PROGxx member from a LNKLSTxx member?
The default for APF processing has never changed from "static table"
(there's a "dynamic format" operation to make it dynamic, but it's best if
that is identified during IPL to avoid wasting space). Are folks using a
dynamically format APF list? (i.e., the APF FORMAT(DYNAMIC) statement in
PROGxx, or SETPROG APF,FORMAT=DYNAMIC)?
When we implemented dynamic APF, there were a few IBM and ISV products
that needed to be enhanced to accommodate it, so we could not
unconditionally change to dynamic format. I hope that all such problems
have long ago been resolved, but we have still left control in the hands
of the customer. Note that you can switch to dynamic after IPL, but it is
a bit "better" to have identified during IPL that the format is dynamic if
you have no problem areas remaining that require the static format.
Thanks.

Peter,
I still see sites using LNKLSTxx, but I don't see sites using IEAAPFxx
anymore. As far as why, if it ain't broke, don't fix it. A statement
from IBM that LNKLSTxx is deprecated could incentivize the switch. Can
you write a health check to encourage conversion from LNKLSTxx to PROGxx?

Tom Conley
