Re: MCH3601 - Pointer not set for location referenced -- MIDRANGE-L

Paul:

For any "3rd party application" I think you should be opening an incident with that vendor's customer support help desk ...

Do you have source code for this application? If so, then you might try to look at statement 59 in procedure DoProcess in module APIPROC2 in program (or service program) APIPROC ...

Do you have any "custom modifications' to this "3rd party application"? For example, do you have any code written by someone in your shop that calls one or more programs or procedures that are part of this "3rd party application"? If so, it is possible that one of them is calling this procedure incorrectly, for example, not passing the required number of parameters, or passing a "null pointer" where a valid address is required, etc.

It might help if you could identify the vendor in question and the name of this particular "3rd party application" ...

HTH,

Periodically, our one 3rd party application results in a MCH3601 Pointer not set for location referenced. A pointer was used, either directly or as a basing

What could be the cause of the MCH3601?
What can be captured to resolve the issue?
