How can I do this without using else if?:
if balls == 0 & ( x > 5 OR y > 7)
run xscript
end
Thanks,

what I meant is that I can use else if to do the above, but how can I avoid having to write the commands twice like this:
if balls == 0 & x > 5
run xscript
elseif balls == 0 & y > 7
run xscript
end
end

use '||' for OR command (without quotes).

You need two &&:
if balls == 0 && ( x > 5 || y > 7)
% run xscript
xscript();
end

@Aadil: Simply ask Google for "Matlab &&" and you weill immediate get: http://www.mathworks.de/help/techdoc/ref/logicaloperatorsshortcircuit.html, which refers to http://www.mathworks.de/help/techdoc/ref/logicaloperatorselementwise.html. Or type "help or".

I've seen that before - where the vertical lines don't appear. However I can't reproduce anymore. For me | appears both in regular text, and code formatted text. By the way, I edited by answer to change "run xscript" to be just "xscript" since the "run" command like you had is not needed.
