Description

The $GUI setting determines whether the application runs in character mode or with a Windows graphical user interface, for this application session.

You can use the ProcScript function $gui to test for the GUI driver in use, allowing you to customize processing for applications which may run under both.

Setting $GUI overrides the GUI driver selected during installation.

Character Mode

In character mode, proportional font spacing and pixel-based screen painting are not possible. Some types of widget are unsupported, in which case they are displayed as Unifields.

The path to the character mode driver is $CHR. If, for example, you want to run an application in character mode, while the default GUI driver selected at installation time was $MSW, you could use the following assignment: 

$GUI = $CHR
