Really? There’s lots that it could do? So why not just read the DSCB
for how much is free and do the calculation that has been on every 3390

This is done all the time and in a variety of ways. This problem was readily
assessed for decades using a subroutine. This has always been something that
could readily be done until people start putting language restrictions on it.
It isn’t that the info isn’t available, it is simply that the information isn’t
available given the restrictions placed on the problem

records there, or do I load it into a VSAM file for direct access? Do I invoke
an external sort or use an internal sort? Or a thousand other things.
It is wrong as @Shmuel points out to preclude questioning the necessity of
doing something exactly as the OP suggests. It is equally wrong to assume there
could be no good reason for doing it the OP's way.

non-database files?
It is easy to say that a COBOL program needs to “know” this but it is
nonsense since there is nothing a COBOL program can do with this info.
If it turns out to really be necessary then a subroutine can be written (as it
has been done for decades) to provide this information.
If the question is simply to bitch about why z/OS does do this automatically
via a call or something then the complaint is directed to the wrong group
