The idea is to produce something that is easy recognisable as done
on purpose and not to muddy the water more for this unexpected
situation.

The idea that a desired USER ABEND is best achieved by triggering a
SYSTEM ABEND that will be minimally confusing, highly unlikely to be
confused with the corresponding real SYSTEM ABEND, does not seem to
want to die.

Binyamin is talking nonsense.
A USER ABEND has the same DUMP options available to it that are
available to any other ABEND.
The notion that the default options supplied for, say, a judiciously
chosen SYSTEM OCx ABEND can somehow be better than those chosen in a
considered way for a USER ABEND is

Personally, I do the S0C1 for one reason alone: for

Use IFGACB macro to map the fields in the ACB. Establish addressability to the
generated ACB area and plug the DDNAME into the ACB ddname field. The other
macro of interest is IFGRPL for manipulating the RPL.

What form would you like a DDNAME value to take?
Given that the DDNAME value is a character string, I suspect the OP
would like the macro to take an address of a character string as
an argument.
