Um...directly above it should be this line:

 -- In Euphoria 2.1 this file (unless modified) is FREE - 0 statements.

It's the "with" line that actually "tells" Euphoria that the include file is
"free."

If you're looking for a single char, use single quotes around the space.

However, if you're comparing string values, you have to change the "if" line
to this:

if not equal(v[i], " ") then
 -- or
if compare(v[i], " ") != 0 then

Remember, the double-quoted string " " is equivalent in Euphoria to the
sequence {32}. If v[i] is an atom, then the expression v[i] != " "
evaluates to {1} or {0}. This is why you're getting the error message
requiring your condition to be an atom, because it currently isn't. You
must use equal() or compare() for conditional logic involving sequences
(or strings -- they're the same thing in Euphoria).
