 The general form of the Allocate Device command is:
 
 ALL[OCATE] dd[nn:]  [=llnn:]

 ALLOCATE establishes the specified device as the user's private device on 
 multiuser protection systems..  The LLnn: keyword allows the
 user to equate a physical device with a logical device.  Specifying the
 command with only a 2 character abbreviation allocates the first free device
 of the type specified.

 Mounted devices, public devices, or other users' private devices cannot be
 allocated.

 The system automatically deallocates a user's private devices when the user
 logs off.
