If we're going for a feature request, I'd suggest a new function "shuffle".
It's more descriptive than 'sort'. (We're trying to do the opposite of sorting.)
I'm also uncomfortable with using arbitrary high numbers. (How random should it
be?) When i've done this before, I've used the analogy of pulling names out of
a hat. So a custom function like this (for shuffling lines) rather than use
sort.
function shuffleLines pSource
put empty into tNew
put the number of lines of pSource into tNum
repeat with n = tNum down to 1
put random(n) into tRand
put line tRand of pSource & cr after tNew
delete line tRand of pSource
end repeat
return line 1 to -1 of tNew
end shuffleLines
Probably a little slow for large lists, but for things like shuffling answer
choices in a test, it's good enough.
Cheers
Dave
