if DSN is migrated
The OP wrote "non-existent", not migrated. The message is appropriate
for a new DASD dataset with no SPACE specification.
But it's inappropriate that the OS create a new data set when it knows
that it will be deleted immediately, never used.
<SNIPPAGE>
How does the O/S know that this data set will never be used? Is
it because of the PGM=IEFBR14?
Can't I have a STEPLIB with IEFBR14 in it?
Suppose that I am using some utility that needs works space. So I do:
//SYSUT?? DD DSN=A.B.C,DISP=(NEW,DELETE),SPACE=(CYL,1000),
// UNIT=3390,DCB=(WHATEVER)
The system should just KNOW that it should not do the allocation
because it's gonna be deleted any way?
Do you have any idea how many SEV1 Critsits IBM would be looking
at if they were to suddenly do this?
