User-input Area

The two bottom lines (lines 23 and 24) on the screen are the user-input area. You can enter up to two 79-character segments of input. When you are not entering data, the cursor is located at the beginning of this area (column 2 of line 23).

Message Format Service (MFS) returns the cursor to this location when a response is received for the entered data. MFS leaves the entered data on the screen and you overlay it with your next input.

A 3270 master terminal using the MFS master-terminal formatting option is normally in unprotected status. This means that IMS can send output to the terminal at any time. You can put the terminal in protected status by pressing the PA3 key or the PFK11 key before entering input data.

The MFS-supplied master-terminal format defines literals for nine of the 3270 program function (PF) keys. The PF keys, when used with the 3270 master terminal formatting option, generate specific IMS commands. Pressing a PF key inserts a command into the first segment, in front of the data. The commands associated with the nine PF keys are:

PF Key: Command/Function

1: /DISPLAY
2: c
3: /DISPLAY STATUS
4: /START LINE
5: /STOP LINE
6: /DISPLAY POOL
7: /BROADCAST LTERM ALL
11: NEXTMSGP
12: Copy (3270 remote)

When pressing the PF7 key to enter the /BROADCAST LTERM ALL command, make sure the first line of input in the user-input area contains only the command. The second line of input should contain the data to be broadcast.

When you use the master-terminal format, MFS displays any message whose MOD name begins with DFSMO (except DFSMO3) in the message area. MFS displays any message whose MOD name is DFSDSPO1 in the display area. Messages with other MOD names cause the warning message USER MESSAGE WAITING.
