Hi Kevin,
If you don't have any allergia with regex, here is one solution:
Code: Select all
if matchText( S, "\+(\d+)}.+\+(\d+)}.+=(\d+)]", n1, n2, n3) then
put "Find: " & n1 && n2 && n3
else
put "Sorry, no match!"
end if
Just typed it out of my head, so beware of possible typos.
Best,
Thierry

Thierry can do more with one line of regex than I can in a handful of lines of "ordinary" code.
But are you OK with that, or do you want to talk about those handfuls?

Hi Craig,
Mmm, I have nothing to do with this fact; that's the power of regex: concise and powerful for
pattern matching.
But are you OK with that, or do you want to talk about those handfuls?
Well, I think it will be nice to have some 'Livecodish' solutions, and let the readers learn,
compare and experiment out of them.
My 2 cents,
@Kevin: Re-reading my post, I've noticed there are some room for speeding up the regex.
If you feel it's too slow, just let me know.
But now, I have to unplug all my computers as a big storm is coming.

JAMAIS, mon ami!
I still consider this WITCHCRAFT!
Have a nice weekend!
