Hi, as parse being a native! it does quite some magiv behind the scenes.
It's the only (?) dialect not written with Rebol, which is logical because
you would need a parse ;-). So the parse dialect just assigns the current
position in the script to your mark: and restores is with :mark.

I don't expect that parse offers something from the internals. But I can
be wrong. I strongly suggest that you look into Gabriele's compile-rule
dialect. It helps a lot when writing more complex parsers. Robert
