  "This procedure gets a command for a file mgr command handler to
  "execute. The procedure is part of the Controller Submodule.
  "The caller need not be aware of whether or not a DMA is in use. This
  "procedure may cause a waiting point. The caller can be sure that the
  "command he is given is within the range of his commands, but it could
  "still have an illeagl command id.
  "On return from this procedure, <cmd op> will contain a command operation,
  "as defined in CMD_OPERATION.


import procedure reply_cmd(
                   r4;  "ref to a port

  "This procedure sends a reply to the user, that signals the completion
  "of his command. The procedure is part of the Controller Submodule.
  "The caller need not be aware of whether or not a DMA is in use, but
  "should be aware that if it is, then a waiting point may occur.
  "The PORT parameter must specify the port at which the command was
  "received (by GET_CMD). The REPLY should hold the 3 words that the
  "caller wants returned to the user. After this procedure, the
  "command handler may not engage in any further communication with
  "the user, involving this command.

  "This procedure transfers data between the user and the File System.
  "The File System data that is to be transferred is specified by the
  "transfer list whose first element is the tle field of <port>. This
  "transfer list also specifies the amount of data to be transferred :
  "that is the data is transferred until this transfer list is exhausted
  "(signified by a link of 0 in a tle).
  "To build this transfer list, transfer list elements may be taken from
  "the pool of TLEs by calls of the procedure GRAB_TLE, and returned to
  "this pool by RETURN_TLE.
  "The user's data is specified by that part of the port which represents
  "the user's current transfer list and it's state.
  "The caller need not be aware of whether a DMA is in use or not. He should
  "realise, however, that in a dual processor system, this procedure may
  "cause a waiting point.
  "Regardless of whether or not a DMA is in use, the transfer may go
  "wrong. This is indicated by the returned <DMA completion code>.
  "Side effects of this procedure will be the updating of the state of the
  "user's transfer list and the destruction of part of the tle field of
  "<port>.
  "This procedure is part of the Command Controller Submodule.

  "whether or not a DMA is in use, except that in a DMA system, this
  "procedure will cause a waiting point.
  "The data to be transferred from the user's data area is specified by
