The ASCII value for a hard space is 202, and unfortunately the answer
depends on what you've got in your container. If you have:

(CR)
(spc)(CR)
Test1(CR)
Test2(CR)
(CR)
(spc)(CR)

when you do word 1 to -1 you get:

Test1(CR)
Test2

However, if the container is:

(CR)
(hardspc)(CR)
Test1(CR)
Test2(CR)
(CR)
(hardspc)(CR)

when you do word 1 to -1 you get:

(hardspc)CR
Test1(CR)
Test2(CR)
(hardspc)

This is why I use the regex expression for my "stsTrim" function instead of
"word 1 to -1"... it's not as elegant, but it *does* handle all the
situations.

function stsTrim pWhat
  local tRetVal
  get matchText(pWhat, "(?s)^\s*(.*?)\s*$", tRetVal)
  return tRetVal
end stsTrim

But if you know for sure that you won't be dealing with hard spaces, "word 1
to -1" is really elegant and easier to use I'd think.
