Hi,

I have few doubts in cobol compiler proc IGYWCL.

To use this proc the cobol source program and copybook (if used) is specified using

Code:
//COBOL.SYSIN DD
//COBOL.SYSLIB DD


respectively, but I couldn't find SYSIN & SYSLIB in COBOL step of proc IGYWCL. So how are these being overridden?

Also, in link edit step LKED has got

Code:
//SYSLIN   DD  DSNAME=&&LOADSET,DISP=(OLD,DELETE)
//         DD  DDNAME=SYSIN <--- second line


I couldn't understand the second line. What it does?

For your reference the below link will take you to the compiler:

Hello,

If a stepname.ddname is specified and the ddname is not already in the proc, it is added to the jcl of the step (you will want to get a copy of the jcl manual and store it locally for easy use - linked to from this site).

The ddname=sysin says that there will be a dd statement in the submitted jcl (not the proc) that has the ddname SYSIN.

Dick,

Thanks for the reply but I am not very clear with second query.

I can't think of any practical scenario where this will be useful icon_confused.gif . Can you please give an example where this is/can be used?

Hello Dinesh,

Look at other compiles at your location that use this PROC. Some (maybe all?) may have linkedt control info in the SYSIN for the LKED step.

It may be helpful to check with the people there who support the compilers and link editor. They should be able to explain the plan behind how this is configured in your environment. This can vary considerasble from place to place.

The way this would be used is to provide additional info to the linkedit step.
