Numeric
The Height switch determines the number of lines on the PWB screen. The Height switch can have one of these values: 25, 43, 50, or 60. The last setting of this switch is saved and restored across PWB sessions and for each project.
Height: first screen height
When you start PWB for the first time, PWB uses the current screen height. Thereafter, PWB restores the previous setting until you explicitly assign a new value to the Height switch.
Note that when you change the setting for Height in the Editor Settings dialog box, the change does not take effect until you choose OK. Other switches takes effect immediately when you choose Set Switch.
