[REBOL] Error trapping

From: carl:cybercraft at: 24-Dec-2003 22:51

To capture an error object you can use something like this...
>> error? err: try [1 / 0]
== true
>> probe disarm err
make object! [ code: 400 type: 'math id: 'zero-divide arg1: none arg2: none arg3: none near: [1 / 0] where: none ] but if the TRY block returns nothing it doesn't work...
>> error? err: try []
** Script Error: err needs a value ** Near: error? err: try [] To get around this you can ensure your TRY blocks always return NONE or FALSE when they otherwise wouldn't return a value, but is there a simplier way? -- Carl Read
