Hi, Alex. Since technique 3 involves counting the items and then for each
item twice extracting a substring, perhaps a technique 4 is worth comparing:
put 1 into tOffset
repeat forever -- no counting the items
put item 1 of (char tOffset to -1 of tData) into tItem -- single
extraction per item
if tItem is empty then
add (the number of chars in tItem) + 1 to tOffset
-- do something useful with tItem
Is it any faster on your data?
