Hi Ganga,

ProgA is compiled separately.

ProgB is statically calling ProgC.

In static call the subprogram is compiled and link edited into the main program.

So progC is precompiled and compiled and it is link edited into ProgB to form a Single Load module for ProgB and ProgC.

as per my knowledge,it depends on 2 things.
1) whether your shop is using package or plan for DB2 programs.
2)programs are called dynamically or statically

a)if your shop is using plans with out packages you need to compile/rebind all the three application programs irrespective of the type of call.

b)if you are using packages and if all the calls are dynamic, then you need to compile/rebind only PGM C. No need to bind A and B since they are not changed.

c)In the scenario in question,If you are using package and since B&C are statically compiled you need to compile/rebind B and C. Not A.

Please let me know in case of any mistaked i made.
