Thanks everyone...
Ryan and Gabriele both suggested I put my script in a block, and Ryan noted
a bug where that the outer block needs to be preceeded by ^/ or #{0A}.
Unfortunately this strategy still does not work inside a binary file. Nice
try ;-) Maybe next version ??

Hi Jason, Ryan,

Rebol was designed to be run when imbedded into other data,

having to clean it first.

So, you can 'do %image.png if the script itself is stored in

Are you saying REBOL do currently parses a binary automatically, and looks
for text containing script in a block ?

I would be surprised and very delighted if this is true now.
Somebody show me an example please!

Hi Ryyan
I don't quite understand you.
Hey Jason,
I was mistaken in that my last example only worked well in a prefaced

There is a problem I discovered, a bug probably. Seems that the null characters
