This function takes advantage of the recursive nature of custom functions move along a set of word (as in a sentence) and stack those words into a return-delimited list. The function stacks one word each recursion until the set is exhausted and returns the result back up through the recusion sequence.

We used this to form a key field pointing relationally to a table of words to determine the existence of words from that table in the sentence of interest.

This is my Custom Function and I want to edit it

Nest as appropriate.
For example, the following will substitute spaces and hyphens with returns.

Substitute ( Substitute ( YourField ; " "; "¶"); "-"; "¶")
