'SIMPLE' (was:Arrrgh! Micro$h*t again.../old basics)

In article &lt;199803182019.UAA27450(a)irwell.zetnet.co.uk&gt;uk>, lisard(a)zetnet.co.uk writes If you've only got 512B of RAM, or a 256B PROM, then yes :-) This is from memory, and is surely wrong in places. I am sure almost all of A-Z did something: A Accept a single keystroke to the 8-bit 'accumulator' C<line> Remainder of line is a comment D Decrement accumulator E End Gn Get variable n (n=0-9) to accumulator I Increment accumulator Jn Jump to the nth '*' in the program Mx Compare (match) accumulator to character x N Skip rest of line if last match was true Pn Put accumulator to variable n R Return from subroutine Sn Jump to subroutine (nth '*') T<line> Type remainder of line to console U User function (user-supplied machine code) Y Skip rest of line if last match was false Hence: C A pointless program *TWould you like to play a game? (Y/N) AMYYJ2 MyYJ2 TOh well, some other time E *TOK, but this is going to be a short game J1 Punctuation characters #$/ etc. were used for editing. The main limitation of the program editor was that you couldn't extend lines once you'd entered them, but you could overtype or shorten them. At one point Peter Gutmann was going to hide this inside 'hpack', I'm not sure whether it ever made it in. -- Lawrence Wilkinson ljw(a)formula1.demon.co.uk The GirlFrendo homepage: http://www.formula1.demon.co.uk/girlfrendo/ "You've got the brains, or so you say, maybe you see things another way"-bis
