Re: ZX80 comparators with negative ressults...
Commodore basic is Microsoft basic.. so I guess there is not a surprise there. I guess MSX basic report true as -1 too? Tiny Basic was a kind of a "open source" proyect in response to the Microsoft basic being heavy and expensive.. they used the (c)copyleft and wrong reserved marks.... as far as I s...

12 LET X=1 13 LET Y=1 14 LET G=0 15 LET S=0 16 LET M=0 Should be: 12 LET X=PI/PI 13 LET Y=X 14 LET G=TAN PI 15 LET S=G 16 LET M=S It's now a perfect tutorial !!!
