Description
The alternate screen sizes corresponding to the different models within the IBM 3270 family of terminals
These sizes are available at command level and during output from User Language statements. For all values except MODEL=5, they also are available for User Language screens and menus and the Full Screen Editor.
For MODEL=5, User Language screens and menus use the full height (26 available lines), but only up to 80 columns of width. In addition, if MODEL=5, the Full Screen Editor uses the size corresponding to MODEL=2.
For terminals communicating through SNA Communications Server, CICS, IUCV, or TSO, Model 204 automatically sets MODEL to the appropriate value when the session begins, provided that the size of the output page buffer (LOUTPB) is large enough to hold the new screen size.
If you set the FSTRMOPT parameter to 2, the MODEL parameter is not reset dynamically. When the value of MODEL is reset from 2 (the default), the values of the OUTLPP, OUTMRL, and INMRL parameters are adjusted accordingly, as shown in the following example.
The screen-size parameter settings for IBM 3270 terminals are shown in the table below.
| MODEL | MINIMUM LOUTPB | OUTLPP | OUTMRL | TERMINAL INMRL | TYPE |
|---|---|---|---|---|---|
| 1 | 1170 | 11 | 80 | 78 | IBM 327x Model 1 |
| 2 | 2130 | 23 | 80 | 78 | IBM 327x Model 2 |
| 3 | 2770 | 31 | 80 | 78 | IBM 327x Model 3 |
| 4 | 3650 | 42 | 80 | 78 | IBM 327x Model 4 |
| 5 | 3774 | 26 | 132 | 130 | IBM 327x Model 5 |
| 6 | custom | custom | custom | custom | Custom tn3270 setting — see "Terminal MODEL 6 support" |
Note: The 3278 Model 2A and the 3279 Model 2C system consoles are not supported in full screen mode.
The values of OUTCCC and INCCC can also be affected. If they are greater than the new OUTMRL and INMRL values, they are set equal to the new values. If they were originally equal to OUTMRL and INMRL, they are made equal again. For example, if the original value of OUTCCC is 80, resetting MODEL from 2 to 5 also resets OUTCCC to 132.
When MODEL is reset, any existing backpages can no longer be displayed.
