There are two problems with this piece of code. First, the error that
occurs is a syntax error ('0/0' is an invalid date, '0 / 0' is an
attempt to divide by zero, notice the space). And it appears you can't
trap syntax errors -
>> error? try [0 / 0]
== true
>> error? try [0/0]
** Syntax Error: Invalid date -- 0/0.
** Where: (line 1) error? try [0/0]
The second problem is that the set function takes a word (or block) as
the argument. "set/any error" passes the contents of error to set.
Try this -
if error? set/any 'error try [ 0 / 0 ] [
error: disarm error
print [ "Now you can savely work with: " mold error]
]
