443 PLRTAP Handle spurious interrupts and I/O error recovery
following a previously off-line drive while reading
or writing label records.
444 PLRLBP Always clear low order 4 bits prior to checking
for ANSI or EBCDIC "VOL1".
445 PLRLBP Return correct density for unlabeled tapes after
attempting to read VOL1 labels.
446 PLRLBP More of edit 445. DX10/DX20 densities were still
PLRT10 not predictable due to ancient version 1 code to
recognize kontrollers which can do auto density
detection. Remove all knowledge of specific types
of tape kontrollers.
447 PLRLBP Fix loop during backspace operation.
450 PLRDSK Always ask the monitor for the queueing structure
PLRT10 rather than relying on something we GETTAB'd long
ago, since QUASAR can change QUESTR.
451 PLRLBP Allow unprivileged users can't access IBM labeled
which contain an access code of " " (space).
