To add script to a file add the text $script to the top of the file. To enter script add the $ char at the beginnig of a line for example $2 x 2. To enter a range use the # char eg #1to10 will be replaced with 10 lines with 1 in the fist line and 10 in the last. So the first thing the interpriter will do is expand the #'s Anything in {} bracets is evaluated before the user see it so the interpriter will evaluated them next eg. $12/{(#1to5 * 0) +RAND(-15:15)} will give 5 lines of 12 divided by a random number in the set [-15..15]. {} bracets can't be nested as it makes no sence. function syntax rand(1:3) $Decimal points //sets the number of snifficant decimal points
