$RELEASE Card
A card of the format
1 16
$RELEASE Unit-function-name
releases the unit assigned to the functional unit 'unit-function-name' from system use, and makes it generally available. Thus, it is possible for object programs to make use of almost all units on the machine, if necessary. For obvious reasons, the system library tape should not be treated in this cavalier fashion.
$EXECUTE Card
Recognition of the card
1 16
$EXECUTE Processor-name
causes the Basic Monitor to position the System Library tape to the named processor, read in the first record, and relinquish control to it.
$IBSYS Card
A card of the form
1
$IBSYS
returns System control to the Basic Monitor, and prepares it to interpret control cards. It is the one control card which must be universally recognized by all participating processors in the system, in order to effect return of control to the Basic Monitor.
$RESTORE Card
A card of the form
1
$RESTORE
restores the Basic Monitor nucleus to its pristine state, as well as preparing the monitor to interpret control cards. The $RESTORE card is used primarily to restore the functional units to their normal (assembled) installation assignment.
