My understanding is, For program A to Link to Program B, program B should be compiled and link edited as a separte program. It cannot be a sub module. Hence I dont think you will need a new plan for program A.

for each version of db2 there is an application programmers guide.
for any subject (programming languages, db2, etc...), the applications programmers guide should be read first.
then, hopefully, one will have mastered the concepts so that the Reference
can be understood.
go to the applications programmers guide for your version of db2 and read the several chapers about CICS.
Therein will you obtain the answer to your question,
and the others that will come as you seem to have little knowledge of your environment.
