List of programs or APIs called by a particular COBOL prog:

Is there anyother ways to get the list of programs or APIs called by a particular COBOL program without scanning the program ?

what do you mean by 'SCAN'?

after you have run your obj thru the binder (actually before) you can run an AMBLIST against the load.

Thanks.

By 'SCAN', I meant ' reading the program line by line, looking for the key word CALL and getting the called program name'.

Let us say we have 10 programs in production. (p1,p2,p3.........)
In that, p1 calls p2 , p2 calls p3 , p3 calls p4 , p4 calls p5.

Now without reading the program P1 line by line, how to know that P2 is called by P1 and so on.

take a look at this thread

Hi enrico-sorichetti,

I went through the thread.

If i am not wrong, the rexx program at the end of the thread (CALLXREF ) will read the COBOL program line by line and look for CALL key word.
( partially i couldnt understand the concept behind the CALLXREF prog )

But what i am looking for is without reading the program line by line, is there any way to know list of programs called by a particular COBOL program ?

DOCUMENTATION!

As Craq indicated, documentation is the key. AMBLIST is a program that can run against a load module and will tell you the components -- presumably including all the static linked subroutines. However, if you have a program doing dynamic calls at run time, AMBLIST won't help you. If the program is CICS then you have to look at the code for sure, as well. Bottom line: documentation (if complete) can tell you but the only way to know for sure is code inspection -- line by line.

What exactly are You looking for ??
if You' d tell Your exact requirements we might give better answers

Sure...

I am working on an impact analyser tool. The tool will list the programs that are accessing a particular table.

For example: I have 10 programs ( P1, P2, P3, P4......). Here the program P5 accesses the DB2 table T1. Also the program p1 calls p3 and program P3 inturn calls P5 ( P5 accesses table T1).

Now the tool have to give the tree like below : p1 -> p3 -> p5 -> T1.

I know how to get the list of programs that hits a particular table directly.

Now I am looking for a way for getting the tree "p1 -> p3 -> p5 " without reading the program line by line.

( I wrote a program in REXX for checking line by line. Since we have huge number of programs to check with, it takes enormous time to figure out. So only I am looking for anyother alternative way to get the tree structure)

I hope, now I have put it clearly.

Thanks for you support.

thanks for the explanation.

So I have to use the REXX program to read the programs line by line.

ok. once again thanks for your support.

I must have had a brain check all this time
there is already a tool to do that...

Hello,

Which will still only work for "things" called statically?

If the called module is not specified until execution, this will still not be able to detect the name to be dynamically called. . .

Which would fine most but not necessarily all modules used.
