Oh, look: I'm like a dog returning to its own vomit:

Useless last time: I wonder what chances this time?
Funny considering a lot of other programming languages do use wildcard
characters (that's a bitchy comment,à l'anglais).

Well, here I am reading my "Revolution 1.1.1" User Guide because when
I was
soaking in a nice hot bath (an excellent location for thinking about
Livecode)
I suddenly thought of a "problem", which, on reflection congealed
around the
term "Wildcard".
Now in the "Revolution 1.1.1" User Guide, page 374 it has this to say:
Wildcard
A symbol that stands for one or more characters.
Which made me think I was back in the bath-tub staring at my navel.
Couldn't find anything else anywhere at all.
Now I was merrily imagining a stack where a source "spat out" new images
every 10 seconds and called them T1, T2, T3 . . . . and so on,
theoretically
for ever, and a "gobbler" (meaning another image) chasing these images
and
messing around with "intersect" as one does.
That, Ding-An-Sich, should not be all that hard.
But the code would be a pain-in-the-bum without a wildcard character.
HOWEVER, I cannot, for the life of me, find out which character IS the
wildcard character in Livecode.
I DON'T want to use Regex as I want to use this with kiddos in
their elementary progging classes this summer.
ALL I can find are refs to matchChunk and matchText.
Now what I need is a way to do this sort of thing:
on arrowkey AK
if AK = "left" then
put item 1 of the loc of img "Gobbler" into G1
put item 2 of the loc of img "Gobbler" into G2
put (G1 - 10) into G1
move img "Gobbler" to G1, G2
end if
---more of the same with "right", "up", and "down"
if intersect(img "Gobbler", img "T#") then
--do something boring
end if
where "#" is the wildcard character.
