I'm a resident too and think this will be great. Big thumbs up.

I have an example of prior art here. There was a company called Trivida in southern California whose software did EXACTLY what this patent is claiming. It was bought by a company called Be Free and they renamed the product BSELECT. It was in use for a time between 1999-2004 by a number of medium sized web sites. Eventually, it was shelved because of lack of demand.

You can look at a press release about version 3.0 of this product (from 2002) here.

Nope. Wrong syntax. String variables required $ AFTER the variable name (which could only be one or two characters; any more characters were ignored. This made BANANA and BALL the same variable.). Integer variables had a % after them. Floating point variables were unqualified.

Also, a comma in a PRINT statement inserted a tab. A semicolon inserted nothing.

The correct syntax should be:

10 B = 9 * 9

20 PRINT "9 times 9 is ";B;". :D"

The math error did happen, though.

Yes, I did this from memory. You never forget your first programming language...
