1. A better way to do it would be to use set/any 'error try [...] as in:
>> either error? set/any 'error try [print "hi"] [
print "error" ] [ print "no error" ] hi no error
>> either error? set/any 'error try [print 1 / 0] [
print "error" ] [ print "no error" ] error ;- Elan [ : - ) ] author of REBOL: THE OFFICIAL GUIDE REBOL Press: The Official Source for REBOL Books visit me at
