@DEVICE-FUNCTION <file name> <function name> (<optional parameter 1>) (<optional parameter 2>)

Performs operation on magnetic tapes, cassette tapes, Versatec printer / plotter and floppy disk.

<file name>
is the name of the device unit, as specified in the @SET-PERIPHERAL-FILE command.
<function name>
is the name of the operation to perform on the device.
<optional parameter 1>
<optional parameter 2>
these two parameters are used to specify more information needed by some operations.

Rules:

  1. Permitted for all users.
  2. The functions READ-RECORD and WRITE-RECORD will transfer a specified amount of data to / from the specified address in the user area (background segment) from / to the specified device unit.
  3. The function UNLOCK-AND-STOP means that the cassette tape will stop and the read / write head will be removed from the tape.The cassette may then be removed from the cassette driver.
  4. The function LOCK-CASSETTE means that the read / write head will be removed onto the cassette tape, ready for read / write of the c assette tape. The cassette tape cannot be removed from the cassette driver when the cassette is in lock position.
  5. The function READ-STATUS will read the status register of the specified device unit by means of an IOX instruction. The function READ-LAST-STATUS will return the status from the last operation of the device without executing any IOX instructions (the status saved by the driver).

Example:

@DEVICE-FUNCTION MAG-TAPE-1, ADVANCE-TO-EOF, 1
