Take a look at Nick Antonaccio's tutorial, it may help:

Rebol does not have a built-in MP3 player. You could try to use the
call function to start an external MP3 player see
http://www.rebol.com/docs/shell.html (call is now available in
REBOL/View).

The argument for the /type refinement must be a REBOL word! datatype:
request/type "your age?" 'info
or request/type "your age?" to-word "info"
When you {enter request/type "your age" info} REBOL evaluates the word
info - it is not set, hence the error. It may seem strange but if you
first set info to the "lit-word" 'info your original statement would
work:
info: 'info
request/type "your age?" info
Victor Pavlu's tutorial has a good explanation of word, get-words,
set-words and lit-words at http://www.rebol.net/article/0201.html
