By seeing the load module can we identify if it is a dynamic call or static call?

[enrico-sorichetti]

if a load module is in a library which is in the linklist or in a steplib/joblib DD

then the load is a main program ( appears in a JCL EXEC statement )
or is dynamically loaded/called

while a module &generated by an high level language
might tell something about its nature and possibly utilization

a pure assembler module will usually tell very little about itself

Do you mean to identify that the program in the load module uses dynamic or static calls, or that the load module itself is called dynamically or statically? You cannot tell from a load module whether it uses static or dynamic calls -- at least, not without a lot more work than would be required by looking at the source code.

This is what I am asking.

[Robert Sample]

A statically called subprogram is linked into the load module of the calling program. There are some cases where statically linked subprograms are compiled individually into a load library and then everything is linked together into the calling load module, but this is pretty rare. The general rule of thumb will be that if there's a load module, as already said, that load module will be either a main program or a dynamically called subprogram.

If I browse the load module of a main program which calls another program statically then some time I saw the called program name there but not always. SO can I say if a batch Cobol program is called by another batch Cobol program and they are in static call, main program load module will have the name of statically called programs?

[Robert Sample]

Yes -- COBOL uses CALL "LITERAL" for static calls and CALL VARIABLE-NAME for dynamic calls. So the program name will be in the literal pool COBOL puts together.

Thanks.

What is literal pool? Are there some more pools in a COBOL program?

What is literal pool?

You could have found the answer by using fewer keystrokes than you used to ask the question. Google 'literal pool cobol'.
