Hi,

Is there any simple method to find out the call chain of a program?

HI es,

When we make some modifications in a sub program, it becomes a tough task to find out all the main driver programs. (If we are going to introduce a new DB2 subroutine all the main programs have to be found out for defining RTT entry for them).

Simiarly if we are going to add a subroutine, all the subroutines called from that has to be found out inorder to make sure that all the required changes are done.

So is there any tool to find out the call chain?

Hello,

If your source is in a common library, you can search the code in library for the name(s) of the called module(s) you are trying to track. You can do this if the source is in a pds or ca-librarian.

if you have endevor, you can use the footprint.

if all your modules are statically linked, you can use amblist with the listload.

otherwise, 3.14 is always a solution.

Hi,

Currently we are searching for the calling modules of the subroutine and in turn their calling modules (we repeat the same process untill we are finished with all the chain). This is the case when we are using 3.14.

Is there any better method to accomplish the same.

We are also not working on endevor.

Hello,

Without endevor or some other similar tool (like changeman), i believe what you are doing is the way to go.

A word of caution - if any of the called modules are specified/determined at run-time (rather than compile-time), they will not appear in any source search.

Hi,

We are using Changeman, how can we use it for this?

Hello,

I'd suggest you talk with your Configuration Management or Change Control people. They should be able to help.

Also, maybe someone here at the forums will post some changeman info - it is a product i've not used (yet

).
