REASSIGN Command
Function
The REASSIGN command passes a device assignment from one job to
another job. Both restricted and unrestricted devices can be
reassigned. When you specify a DECtape in this command, the
system clears the copy of the directory currently in memory. The
next time you refer to the directory, a new copy is read from
tape into memory. However, the logical name that has been
assigned is not reassigned unless you reassign the device to your
own job.
Format
REASSIGN dev:job
Where: dev: is the physical or logical name of the device to
be reassigned. This argument is required. See the
help filr DEVNAM for a description of device names.
job is the number of the job to which the device is to
be reassigned. If no job is specified, the device is
reassigned to your job. This is useful when you want
to force the next DECtape directory reference to come
from the tape instead of core.
You can reassign a device using the logical name only if your job
and the job to which the device is to be reassigned have the same
project-programmer number, or you have operator privileges
(logged in under [1,2] or logged in as OPR).
Associated Messages
If the job number you specify is out of the range of legal job
numbers, the monitor prints:
?NOT A JOB
If no arguments are included in the REASSIGN command, the monitor
prints:
?NOT ENOUGH ARGS
If the device specified is not assigned to your job, the monitor
prints:
?CAN'T BE REASSIGNED
Characteristics

Will not function during device I/O.
Restrictions
