Hi,
The other suggestions will probably bring you to realise this, but I
wanted to make it a little more obvious...
When attempting to catch an error and disarm it for your own error handling
scheme you will find that using 'set/any is needed rather than a set-word
for maximum strength error handling. For example:
Use
>> if error set/any fred try [print "done"] [print "Error!"]
done
>>
Rather than
>> if error fred: try [print "done"] [print "Error!"]
All that try does is catches any error that may be encountered and returns
it in as an Error! datatype. 'try doesn't care if a datatype that cannnot
be assigned via 'set or a set-word is passed, it will only attempt to
'disarm an error within the argument passed to it.
