Yes, you can use the RELATE function of DEFINE (I may have the fields backward,
if so - sorry)
DEFINE ALIAS (NAME(JOEBLOW.FOOBAR) RELATE(SYS1.FOOBAR))
However, make sure the security is setup for people to access JOEBLOW.FOOBAR and
SYS1.FOOBAR the same way.
You can also look at SYMBOLICRELATE
DEFINE ALIAS (NAME(SYS1.FOOBAR) -
SYMBOLICRELATE('JOEBLOW.FOOBAR'))
However, when a data set ALIAS of NON VSAM is created using DEFINE ALIAS
SYMBOLICRELATE and when a DELETE is done against the REAL data set, the data set
alias created using SYMBOLICRELATE is not deleted. This is because the entry is
not associated with any real data sets and it is only a catalog entry.
