Confusing result from position function

[murrayf3]

I'm trying to use the position function to parse URLs. I'm looking for the "." (period) delimiter and I want the position of the one that is nearest to the end of the string.

WIth the rawtext = "demos.su"

Position( rawtext, ".", 1, -1) returns 0

This doesn't seem right. What am I missing?

Try: Position(rawtext, ".", Length(rawtext), -1)

BINGO! Thank you very much.
