Thanks for responding.

You make a fair point and although WAIT does work in this example it
dramatically slows down the program that this code has been ripped from.
Please have a look at...

http://www.riscosbasic.uk/problems/Kill_verticals.zip

Unfortunately the program is not named but I believe it may have been
created by Krzysztof Jankowski and can be found on YouTube. The
original program was done in MODE 28 but I wanted to see if I could
convert it for 1080p monitors. Original mouse cursor has instability
issues but these are magnified in 1920 x 1080 modes.

Scoring logic appears slightly odd - it takes a very short time to build
up a huge score - this may require tweaking.

Richard
