saving Rebol
[1/4] from: gchiu:compkarori at: 24-Nov-2000 7:08
In Forth, when you add new words to the dictionary, you can
save the new forth image so that when executed again, all
the new words are retained.
Is there something like this in Rebol?
And what's the Rebol way of doing conditional compilation?
I would have guessed something like
if ( not exists? clean-script )
[ do %clean-script.r ]
but exists? only works on files and urls.

Can't help you with that one, but...

You can see if words exist using value? So, assuming clean-script.r
creates a word called 'clean-script-flag, the following should work
for you...
if ( not value? 'clean-script-flag )
[ do %clean-script.r ]
Hope that's of some use.

Thanks Carl, that works. Exists? would also be nice :-)

You can SAVE your values and then LOAD/DO them back inside your
user.r.

Try using VALUE? 'WORD.
