I believe (I can be wrong here), that DFSMShsm do it in the following way: it writes data until end of volume, then it moves back a number of blocks. The number is counted as percentage of the tape. You can followe this way or simply use ABARS. BTW: Do you really need to create the TAPES ?

] Subject: RE: How to find current tape length programatically David, For the older 3480/3490 with IDRC, it is much harder. With 3490/E, it is much easier to determine by looking at the block-id. The logical block-ID increases as the physical blocks of data are written out; and then decreases
