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 SOUL statements. For all values except MODEL=5, they also are available for SOUL screens and menus and the Full Screen Editor.

For MODEL=5, SOUL 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, INMRL, OUTCCC, and OUTCCC 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. OUTLPP, OUTMRL, INMRL, OUTCCC, INCCC are all reset automatically as part of the RESET MODEL command.
