I am into a maintenance project of CYBERLIFE. In one of the phases around 800-1000 elements ( COBOL / ASSEMBLERS linked to a load using link cards ) are involved. Whenever a problem occurs it takes hell a lot of time to trace the affected element 1st. Is there any way to get an active call chain of elements flow without modifying the programs?? ( If an abend occurs we do get a reverse call chain ) . Similarly is there any possibility to get the chain for Return Code 0 ??

Hello Arun and welcome to the forum,

If one of the components abends, it should be identified along with the abend info. If you want to know "how you got there", you should be able to trace backwards (assuming all of the participants follow standard linkage conventions). And yes, it can be rather tedious. . . icon_wink.gif

I'd suggest talking with your system programmer(s) for guidance on how to do this on your system.

Thanks for your suggestions. We normally track the flow in an element using Cobtrace func. But to find if an element is there in the flow, it is through hit or miss only.
