ISRDDN – That’s wrong – no, that’s new

I’ve just started using a new system, and I’ve been looking around.

I used ISRDDN to display the allocations for ISPF. It gives

When I browse the top member, I get member data set SYS1.DGTCLIB(ACBQVAO4). This is not in USER.CLIST. What is going on ?

If you look at the output of USER.CLIST is has Lib:8. This means the 8th library in the list of SYSPROC.

Member ADDVOL is in library 1 which really is USER.CLIST

if you browse any other data set under the SYSPROC it has

without the Lib.
