QMHCHGEM API & Invocation pointer

[Paul Jackson <pjackson@xxxxxxxxxx>]

Hello,

I am trying to use the QMHCHGEM (Change exception message) API as a default
handling program for a particular message ID.  Unfortunately the API
requires an "invocation pointer".  The handling program is passed program
queue and message key information but not pointer.

I have been searching through the API's on the web with no luck and am
wondering if there's a method I can use to retrieve the invocation pointer
for passing to the API.

Any help would be appreciated.

Paul
