And don’t forget ‘begins with’. They were both added in v. 2.9.

Ends with.. How did I not know about that?

LAST doesn't return a numeric value (as far as I can tell) so you can't
subtract from it, if you do you get strange results

In addition, the order matters.  You're putting the last char first, and
the second to last char last (if you were allowed to use last that way)  So
if it did work, you'd be checking W$ against $W

You could do it other ways too of course.  You could use (char
length(MNOSE) -1 of MNOSE & char length(MNOSE) of mNose)  to do the
comparison..  Note the -1 is first to keep the characters in order.

Suppose I have a string a bit like this:

"and then the gigantic monster bit my mother on the nose $W"

and I want to check that that string ends with "$W" . . .

I tried this (pseudo code):

*if the ((last char) & (last char -1)) of MNOSE = "$W"*

and it did not work.
