The 3590 hardware details are only available from IBM through a licence,
so if you have the licence you can find the opcodes in the
documentation; otherwise, don't feel bad about not remembering!
Luckily the 3590 accepts most of the ordinary CCWs (read, write, rewind,
etc) that have been defined since the days of 2400 round tape reels,
including DSE (Data Security Erase), so any 3480 or 3490 CCW book will
do. Only the more esoteric things, like query CCWs, mode setting CCWs
and sense are not available publically for 3590s.
As Willie Bunter pointed out (thanks!), our products FATS has the
ability to erase tapes, either totally or after the last file on the
tape. See our web site (below) or contact sales for info.
