This is (whether trueWord or word chunks used) probably the fastest
method for an offset counting of one (true)word.

Possibly it is for a large tSource (say 4 MByte) better to use CR
instead of comma as delimiter for the list:
Else, when putting tOffsetList into a field, LC may cut the result
or even hang (LC 9) because the maximum pixel size of a line gets
exceeded.
