1  DEALLOCATE
   Makes an allocated device available to other processes (but
   does not deassign any logical name associated with the device).
   DEALLOCATE does not deallocate devices that are in use.

   Format

     DEALLOCATE  device-name[:]
 

2  Parameter
 

device-name[:]

   Name of the device to be deallocated. The device name can be a
   physical device name or a logical name that is not in use. On a
   physical device name, the controller defaults to A and the unit
   to 0. This parameter is incompatible with the /ALL qualifier.
 

2  Qualifier
 

/ALL

   Deallocates all devices currently allocated by your process that
   are not in use. This qualifier is incompatible with the device-
   name parameter.
 

2  Examples

   1.$ DEALLOCATE  DMB1:

     In this example, the DEALLOCATE command deallocates unit 1 of
     the RK06/RK07 devices on controller B.

   2.$ ALLOCATE   MT:   TAPE
     %DCL-I-ALLOC, _MTB1:  allocated
        .
        .
        .
     $ DEALLOCATE  TAPE:

     In this example, the ALLOCATE command requests that any
     magnetic tape drive be allocated and assigns the logical
     name TAPE to the device. The response to the ALLOCATE command
     indicates the successful allocation of the device MTB1. The
     DEALLOCATE command specifies the logical name TAPE to release
     the tape drive.

   3.$ DEALLOCATE/ALL

     In this example, the DEALLOCATE command deallocates all devices
     that are currently allocated.
