Hi Anton,
Bit slow on the uptake here ....
If you do a
set/any 'error try [print ""]
How do you test for an error?
any time I try to do anything with error I get an error :-) .... for example
>> print error
** Script Error: error has no value
** Near: print error
Cheers Phil

Good site.
Bad colours - that's ok! I set my browser
to overide your colours with my preferred
colours. >:D
In the errors handling document, I think you
should set people to use
set/any 'error try
rather than
error: try
because in some cases the second one leads to another
error. For a beginner that would be frustrating.
eg:
>> error: try [print ""]
** Script Error: error needs a value
** Near: error: try [print ""]
print returns an unset!, so there is nothing to
set error to, and a new error is generated.
Anton.
