I only wanted to give some information to use for a decision in a script.
So if you just want to trim spaces or any of a bunch of characters from the front _or_ the end,

 "while char 1 of testString is space"
or
 "while char 1 of testString is in myCollection"
will do a good job and be crystal clear.
"Token" is surprisingly slow, and "word" is very effective if you can control the situation.

> word 1 to -1 of testString   -> removes tabs, spaces and returns from  

But do you know what you get if you ask for

get word 1 to -1 of quote & "    My test with lots of spaces at the end     "?

All the best
Thomas
