Same idea. If you have an error
you must disarm it before looking at it.
Let's go back to the tried and true method
which I use all the time:
either error? set/any 'err try [...][
; An error happened
err: disarm err
probe err
][
; No error
; err is set to the result of doing the
; code block, though, so
; err might have a value or unset!
]
