How do I find multiple instances of a string in a given field of a

It's simpler than you'd think. Unlike HyperCard, LiveCode reports "not
found" as soon as the last instance has been located. So all you have to
do is repeat the find command until the result is "not found". You don't
have to manage any card or field loops, the engine does it all.
Off the top of my head:
put "thing to find" into tVar
repeat
find tVar [in field "thisField"]
if the result = "not found" then exit repeat
put the foundchunk & cr after tFoundList
end repeat
This will go through all the cards and fields by itself. I didn't test
it, so you do that. ;) I probably forgot something.
Note that if you interrupt the find command it will lose its place, so
let the repeat loop continue until it's done.
