Using RACF, it is possible to set up a SETROPTS which will prefix all
"single level dataset names" with a given high level qualifer. If this
is done, it would be possible to create a RACF rule for "hlq.NULLFILE"
with a UACC of ALTER. I would likely do this as a global dataset rule.
As an example, suppose this qualifer is "NONE.". Then you could create a
rule similar to:
SETROPTS PREFIX(NONE)
RALTER GLOBAL DATASET ADDMEM('NONE.NULLFILE'/ALTER)
SETROPTS GLOBAL(DATASET) REFRESH
Now any DSN access to DSN=NULLFILE will do a check on DSN=NONE.NULLFILE
and match the above rule.
