Example

 $ ALLOCATE CR:
   _CRA0: ALLOCATED
 $ SET CARD_READER CRA0:/029
 $ COPY  CRA0: [PEARLMAN.DATAFILES]CARDS.DAT

     The ALLOCATE command requests the allocation of a card reader
     by specifying the generic device name. When the ALLOCATE
     command displays the name of the device, the SET CARD_READER
     command sets the translation mode at 029. Then the COPY command
     copies all the cards read by the card reader CRA0 into the file
     CARDS.DAT in the directory [PEARLMAN.DATAFILES].
