Calling program(Assmbler/Cobol)

Hi,

I have small doubt, could you please.

Assume i have a Main program (COBOL) and sub program (ASSEMBLER), then when i try give a call, the assembler treats COBOL as main and ASSEMBLER as sub program, its fine.

Assume when i have a main program (ASSEMBLER) and sub program (COBOL) does the assembler treats ASSEMBLER as main and COBOL as sub program, to treat it the same what changes do we need to do in JCL.

please correct me if iam wrong.

thanks in advance.

regards,
Munna.

Your understanding of things is pretty messed up

the called <whatever> is NOT aware of the <caller>

the only constraint is that the called thing must be passed the proper parameters

an assembler subroutine does not need any ENVIRONMENT setup

a HIGH LEVEL subroutine needs to have the proper LANGUAGE ENVIRONMENT prepared

If you are calling Cobol from Assembler, your Assembler program should be "LE Compliant". You might want to start your research with something list this topic.

If this is a Batch environment, review adding CEEPIPI (temporary LE compliance stub) to the Assembler Main-Caller or (as Bill has suggested), making the Main-Caller permanently LE compliant for the HLL sub-program.

It's not too often that Assembler calls COBOL (or any other HLL) as it's normally the other way around.

CEEPIPI cannot be used in a CICS environment.

hey enrico ...

my intention was...

If we call a sub program as Assembler or Cobol vice versa. The compiler assumes Cobol as the main entry point. It is fine when we are calling Assmbler program as sub program. But when we are calling Cobol program as sub program from Assembler program as main program, then at that time we have to do some changes in JCL.

Do you have any idea about the changes to be made in JCL.

Actually, the changes would most likely be in the linkage editor / binder statements and NOT, technically, in the JCL. If you do not understand the linkage editor / binder commands (such as ENTRY, INCLUDE, NAME) then providing any further details would be useless.

i know the way to do it, but wanna double check from others.

here to go:

//L.SYSIN DD *

INCLUDE LIB1 (cobol pgm name)
ENTRY assembler-pgm-name

/*

if there are any other ways to do it, pls drop your thoughts.

Hello,

Why do you Not wanna try what you have and then post if there are questions or problems. . .

Now i dont have environment to test it. since its long time being away from technical stuff(coding etc) now im into management. i hope you understand.

Hello,

Now the understanding is a bit better

Suggest you arrange to have a logon id set up so you can run some things "on your own" and look arounf the system. Most of the managers i've supported have a "developer" logon even if they rarely use those tools.
