I just added this programme to www.fishsta.co.uk
This is one from the British TI Home Computer Users Club Newsletters, but what got me was the clever way John Stocks has got the TI to convert X/Y Co-ordinates into a CHAR string to compute the graph.
Has anyone seen anything like this used anywhere else? To some here, it might seem simple, but to me, it's almost incredible that someone could convert a sequence of X/Y co-ords into Hexadecimal code by means of a formula, and produce these results.
He says the first few lines are editable, so in theory we could produce easy SIN/TAN/COS graphs, or even random graphs.
Admittedly very slowly. You will probably want to overdrive it.
Other well-known computers, such as the Spectrum, had the PLOT command, which is obviously sadly absent in standard TI Basic.
Anyway, if anyone can come up with interesting lines to replace lines 100-120 in this programme, I'd be curious to try them myself.
