I don't fully understand what you are doing here, but would the following be
useful?
function offsets str,container,includeOverlaps
-- returns a comma-delimited list of all the offsets of str in container
-- returns 0 if not found
-- third param is optional:
-- offsets("xx","xxxxxx") returns "1,3,5" not "1,2,3,4,5"
-- ie, by default, overlapping offsets are not counted
-- if you want overlapping offsets then pass "true" in 3rd param
if str is not in container then return 0
if includeOverlaps = empty then put false into includeOverlaps
put empty into offsetList
put 0 into startPoint
repeat
put offset(str,container,startPoint) into thisOffset
if thisOffset = 0 then exit repeat
add thisOffset to startPoint
put startPoint & comma after offsetList
if not includeOverlaps then
add length(str)-1 to startPoint
end if
end repeat
return item 1 to -1 of offsetList -- delete trailing comma
end offsets
