Kalpana,

Depends on what sort of problem you are facing.
But usually you find the next sequential instruction to be executed, then see that offset in the listing.So that you will the exact location of the problem.
Let me know if you need something in specific.

Regards

Kalpana,

IPCS is the tool most widely used in S/390. You can collect information about the TCB by following CVT -> TCB1 -> TCB2 ....

Hi Kalpana,

We have got many tools to read the created dump. And they is always our PSW to check for the offset and go to that instruction where it abended. If you are very good, you can also dig the work areas created in the dump.

Thanks,
Virgon

Hi Kalpana,

Generally, dump will contain the error code and information related to the Program Status Word (PSW). This PSW consists of the next instruction address that will excuted once after the assembler statement which has created the error/dump. So, u take the next instruction address and search for this address in the listing you will find an instruction which has not executed yet because of error/dump created by previous instruction.
Then you go to the previous instruction and check for the instruction type and other things based on the error message that you are getting.
