Description
The SET SCREENIO command allows the programmer to handle processing of the special screen attributes character, CHR(255). Standard processing uses the screen attributes character to mark sections of the screenmap for special video attributes such as blink or reverse. The SET SCREENIO command allows for temporary disabling of the processing of CHR(255).
If SET SCREENIO is OFF, special processing is disabled and CHR (255) is displayed as a space character.
Example
set screenio off ? chr(255) set screenio on
