Not always,
I know words are unique but... can hapen that one word is part of another.
Look at this case:

"I allways go that way"

if you try to look for way with at() you will get 6th position, but it isn´t the position of the word "way"

Exactly, I have this:
lcStr="word1-word/word3-word2/wor"

and the function GETWORDPOSITION (lcStr,5) must return 24.
Does this function exist, or how can I get it?

Thanks again,
Ibai
