Sign on to a workstation session that is defined to allow 27×132 — this is a setting in the emulator on the PC.
Once the workstation device is capable of displaying 27×132, then you would simply display a 27×132 record format. (System displays will automatically adapt to the display size of the device.) The DDS for a display file would be created to handle either 24×80 or 27×132 or both.
The DDS file-level keyword is DSPSIZ(). It can have parameter values of *DS3, *DS4 or both. It can have some other values, but they all translate to one of those two special values.<ul>
<li>*DS3 indicates record formats designed for 24×80.</li><li>*DS4 indicates record formats designed for 27×132.</li>
You can only display *DS4 formats on devices that are enabled for 27×132.
