Operator control tables
Input device fields can be defined to invoke MFS control functions when either the data or the data length satisfies a predefined condition. Do this by defining one or more operator control tables and including the related table name in the device field definition.
When a device field is defined with an associated operator control table, MFS processes the device input field and performs the requested control function if the input data satisfies the conditions of the operator control table.
The following control functions are available when you use operator
control tables:
- NEXTPP
- Provides the next physical page of the current message.
- NEXTLP
- Provides the next logical page of the current message.
- PAGEREQ
- Provides the logical
page requested by the second through last characters of this field.
PAGEREQ functions are specified as in operator logical paging. The
first character is a page request
trigger
character that you define. The remaining characters must be n[nnn], +n[nn], -n[nn], or L (an equals sign (=) is not allowed). - NEXTMSG
- Dequeues the current output message and provides the first physical page of the next message, if any.
- NEXTMSGP
- Dequeues the current output message and provides the first physical page of the next message, if any; or notifies you that there are no other messages in the queue.
- ENDMPPI
- Terminates a multiple physical page input message. Available only for the 3270.
Unlike operator logical paging requests, these functions are always located by MFS during the editing process.
