**** NOTE: not valid for Scratch 3 **** --- This was written for Scratch 2 --- =========================== Just a quick test, adding clickable scripts to gor-dee's project, so it's a bit clearer what's being compared and what's going on. Basically, Scratch takes a bit longer to 'process' a string with more digits than one with fewer digits, so it's slightly quicker to check, for example, if something=0 rather than something=100000000000. That has slight consequences for loops, since it means something that does loads of looping with repeat until is ever so slightly better off counting down and checking against zero rather than counting up and checking against, say, a million. -Tiny difference, though...
