Maybe I'm missing the point here, but...
if error? capture-error: try [do %config.r]
[ print ["Whoops! " mold disarm capture-error]
]
...should do the trick
There are some REBOL errors that crash the interpretor entirely and don't get
trapped, but a badly formed file name shouldn't be one as far as I know.
Just for interest, one such error (it'll crash 1.2.1.3.1 REBOL) is:
aa: make object! []
bb: make object! aa
The second line should be:
bb: make aa []
