In Reflection for HP, the value of DisplayRows determines the number of lines visible on screen.

In Reflection for UNIX and OpenVMS and Reflection for ReGIS Graphics, the WindowRows property determines the number of lines visible on screen. Changing the value of DisplayRows automatically sets WindowRows to the same value, but changing the value of WindowRows has no effect on DisplayRows. If WindowRows is larger than DisplayRows, the unused part of the terminal window will be blank. If WindowRows is smaller than DisplayRows, only a portion of each display page will be visible on screen, and you will need to scroll to the view the entire display page.

Changing row dimensions in the Screen tab of the Display Setup dialog box automatically sets both DisplayRows and WindowRows to the new value.
