New sign-up, so apologies if this is not in the correct forum!!!
We have just upgraded to 13 from 12 and I have noticed a small anomaly which I was wondering if anyone else has encountered.
Scripts are stored on an IBM mainframe and use the &SYSUSER variable for temporary table builds etc. Under 12, using &SYSUSER resolved to the individual's mainframe logon e,g RichUK whereas under 13 it is resolved to OMVSUSER. We have verified that it is the new libraries that are causing this, but have no idea why.
