Take a look at the docs on try. The usual technique is something like
if error? try [
... some code that might break here ...
][
... do the right thing for breakage ...
]
or
either error? try [
... some code that might break here ...
][
... do the right thing for breakage ...
][
... do the right thing for success ...
]
You might want to take a look at benchweb.r on rebol.org (it was
written early in my efforts at learning REBOL, so I don't hold it
out as a good overall example, but you might pick up a hint or two.)
