MFS control functions (Finance)
The operators of devices using MFS can use a number of control functions.
The control functions available to the operators
of devices using MFS are:
- Page Advance (NEXTPP)
- Transmit the next physical page of the current message, if one exists.
- Logical Page Advance (NEXTLP)
- Transmit the first or only physical page of the next logical page of the current message.
- Logical Page Requests
- PAGEREQ=nn where nn is the number of the logical page desired. If the request is valid, transmit the data fields defined in the specified logical page of the current message.
- Message Advance Protect (NEXTMSGP)
- Discontinue printing or displaying the current output message and begin transmitting the next message in the output queue. If none exists, return an exception DR2 to notify the operator.
- Message Advance (NEXTMSG)
- Discontinue printing or displaying the current output message and begin transmitting the next message, if any.
These control functions can be indicated to MFS by including them in input function management headers or by defining an operator control field within the input data to MFS.
