But on a nightly
basis you do not need to run CLEAR(*YES). You will still have all the
tape space available if you run CLEAR(*NO). Basically it wiped out
the
header and goes from there. Trust me, it just works. We've been
doing
this for decades.
But why, on a nightly basis, do so many of you run INZTAP anyway? Just
start the save at sequence 1 and let the save overwrite the previous
data. By constantly running INZTAP you:
a) wear out the start of the tape :)
and
b) mess up the read/write error statistics for the tape.
Sure, initialise and clear a tape prior to disposing of it but
otherwise a tape should be initialised once and just reused.
