Ahah - I think the email I've just sent may be of use. (: Instead of
using wait in the example I gave, use Graham's wait-till function
instead. Something like this...
times: [12:00 12:30 13:00 13:30] ; etc...
; Main code here
wait-till first times
print first times
times: next times
if empty? times [times: head times]
The 'first gets the first value in the block, 'next moves the block's
index along, and when the block seems empty, (it's not really - it's
just that its ('times's, actually) index is pointing at its end), the
'head word returns the block back to its original state.
