Resolution

The S0C4 is in a User Exit - NMDSN$$D. The module is running in 24 bit mode and attempting to access 31 bit storage. The product supplied module has name NMSECDSN. Need to fix User Exit, Module NMDSN$$D needs to be linked as AMODE 31 not AMODE 24.

Use your ISPF browse of the load library for this NetMaster region and locate NMSEC$$D - it should look like this –

With NMSECDSN being linked as AM 31
