Dar,
It seems to have to do with the size of the string searched, but it
takes a bit more to trigger it.
Try this one in your message box:
put empty into tLongText
repeat 1000
put "This is a string to find things in" after tLongText
end repeat
put "string to find" into tFindText
put the milliseconds into sTime
repeat 10000
get offset(tFindText, tLongText)
end repeat
put the milliseconds into eTime
answer (eTime - sTime)
put the milliseconds into sTime
repeat 10000
get (tLongText contains tFindText)
end repeat
put the milliseconds into eTime
answer (eTime - sTime)
Try changing the first loop from 10 to 1000 to 10000 and watch how much
of a difference it makes. It almost looks like the "contains" operator
keeps on searching even after the first match... wouldn't that be
awfully inefficient! In fact, if it's really doing that for no good
reason, I might say it's a bug- but maybe there's something I'm missing.
