You'll probably want to do a pair of nested repeat loops. The first
loop will cycle through the outer lists; the second loop, inside the
first, will do its thing on the individual entries in the lists. If
the second loop finds its term it kicks out and sets a flag to true
to tell the outer loop to terminate its cycle as well. Something like
this:
on GetArrayPosition, sChar
nAllLists = checks.count
repeat with nFirstPos = 1 to nAllLists
bFoundTerm = FALSE
lSubList = checks[nFirstPos]
nListTerms = lSubList.count
repeat with nSecondPos = 1 to nListTerms
if lSubList[nSecondPos] = sChar then
bFoundTerm = TRUE
exit repeat
end if
end repeat
if bFoundTerm = TRUE then
exit repeat
end if
end repeat
if bFoundTerm = TRUE then
return [ nFirstPos, nSecondPos ]
else
return [ 0, 0 ]
end if
END GetArrayPosition
You'd call it something like:
put lIndexPos = GetArrayPosition( "c" )
-- [4, 3]
put lIndexPos = GetArrayPosition( "q" )
-- [0, 0]
