It happens. Len Shustek's copy of APL/360 has JCL

1600 to 6250 after the label is written. None of my drives can deal with
that, incl the 9610.
I've never tried programatic density switching on the 9610, which is
supported.
Just stick another BOT marker somewhere within the label area, take the
drive offline and hit LOAD, setting your new density accordingly.
AFAIK, no drive pays attention to the BOT status while reading.
