Screen highlights and special effects

Coloured and flashing text:

The system module provides the procedures textborder, textcolor, textmode and textwindow.These can be used to enhance the text screen. For example:

   USE system
     textmode(5) // 80 columns, 50 lines, VGA screen
     textcolor(1,1,3) // blue foreground, flashing, cyan background

Also, in the graphics module, there are the procedures pencolor, setfont, textbackground, and textstyle which provide quite powerful text enhancements.

See the UniComal Development Toolkit Manual, Chapters 1 and 2 (System Module) and Chapters 3 and 4 (Graphics Module) for full details and example programs. Also see the on-line help screens.
