Again, you're giving the right answer to the wrong question. The OP did not ask how many tracks were allocated, he asked for the file size in bytes. Since the OP hasn't told us why he wants the information, it is presumptuous to presume that he should shut up and use something different from what he asked for. Several people have asked him to clarify that point, but he hasn't chosen to do so.

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 Reference card for 30 years 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 Get Outlook for iOS On Thu, May 14, 2020 at 1:56 PM -0700, "Charles Mills" <charl...@mcn.org> wrote: There is lots it could do! Make a decision on "strategy" based on the volume of input, for example. Do I process it all or cut off after 'n' records and do more on the next run? Do I read the file into an in-memory table and access 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.

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 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
