Hi Jeff,
Welcome to REBOL!

== phhocml
What we've done here is set the value of the word W to reference a
word! value created from the symbol, but not created new words from
those symbols.
>> w
== phhocml
>> phhocml
** Script Error: phhocml has no value
** Near: phhocml
Given a word, it's easy to use SET to set it to an initial value. This
will create global words the way I think you expected.
>> foreach symbol words [set to-word symbol none]
== none
>> phhocml
== none
Words, binding, series, and evaluation behavior aren't always obvious,
especially if you're coming from other languages, so don't be afraid
to ask questions if things don't work as expected.
Happy REBOLing!
