INVERSE [ #channel ]


ALIAS (DIY Toolkit - Vol A)

This command provides the QL with a facility which is available on most other implementations of BASIC - inverse video. What this command actually does is swap over the values which have been set for the specified window channel (default #1) for the STRIP and INK colours, thereby making any further text which is PRINTed to that window stand out. This means that for example, if you set the INK to 7 (white) and the STRIP (or PAPER colour) to 2 (red), after INVERSE, text will be printed in red INK on a white STRIP.


STRIP #2,7:INK #2,0:PRINT #2,'This text is normal'
INVERSE #2:PRINT #2,'But this is in inverse video!!'
