1 TMP_QUOTA
 
  This system allows a user to request disk space through the creation
  of a directory and the attribution of disk quota under the current
  UIC on a specific disk SYS$TMP. The allocation of disk space is
  granted only if there is sufficient free space on the disk.
  In case of deletion of the process or system crash, all the files
  created in temporary space are deleted.

2 GETTMP
 
  This command requests allocation of disk space. The number of blocks
  required is specified by the qualifier /BLOC=n.
  This command modifies the global symbol $STATUS and updates the
  global symbol QUOTA$TMP which contains the number of blocks allocated.
  This command can be used several times by the same process ; the
  number of blocks required are added to the previous allocations.
  However, a user cannot simultaneously requests temporary disk space
  in different processes.
 
2 RELTMP

  This command releases all the blocks allocated during the process.
  This command modifies the global symbol $STATUS and updates the
  global symbol QUOTA$TMP which contains the number of blocks released.

2 QTMP

  This command allows a user to known the number of free blocks and the
  current allocations. By default, the user obtains all the allocations
  required by processes within his group. The qualifier /ALL can be used
  to obtain all the allocations in the system.
  This command modifies the global symbol $STATUS and updates the global
  symbol QUOTA$TMP which contains the number of free blocks.

  $ GETTMP /BLOC=20000      requires 20 000 blocks

  $ QTMP                    requires for the number of free blocks
