Shmuel, So what is your answer to the question?
In the meantime, when the minimum allocation unit I can use is a track, and a track has 56664 bytes, the that will be the size of the file. If the op asked how many bytes of data is in his file than I would employ some other method. The OP did not ask how much to allocate - he asked how much is allocated. Factors for block gaps and end-of-track waste are already factored into the existing file allocation. You are operating in the wrong tense. Ron M: An argument isn't just contradiction. A: It can be. M: No it can't. An argument is a connected series of statements intended to establish a proposition. A: No it isn't. M: Yes it is! It's not just contradiction. A: Look, if I argue with you, I must take up a contrary position. M: Yes, but that's not just saying 'No it isn't.' A: Yes it is! M: No it isn't! A: Yes it is! M: Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes. (short pause) A: No it isn't. > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of > Shmuel Metz (Seymour J.) > Sent: Wednesday, December 24, 2008 7:33 AM > To: IBM-MAIN@bama.ua.edu > Subject: Re: [IBM-MAIN] How to calculate size of a PS dataset (no, no yet > again) > > In <003a01c96526$7e55bac0$7b0130...@hawkins1960@sbcglobal.net>, on > 12/23/2008 > at 09:47 AM, Ron Hawkins <ron.hawkins1...@sbcglobal.net> said: > > >The OP asked how to calculate the size of the file in MB or GB.
