Makes an allocated device available to other processes (but does
   not deassign any logical name associated with the device).

PARAMETERQUALIFIER

Examples

device-name[:]
   Name of the device to be deallocated. The device name can be a
   physical device name or a logical name. On a physical device name,
   the controller defaults to A and the unit to 0. This parameter is
   incompatible with the /ALL qualifier.

Additional information available:

/ALL

   Deallocates all devices currently allocated by your process. This
   qualifier is incompatible with the device-name parameter.

   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.
