So why doesn't Jon's method throw an error? Are you not invoking a
method on a class that does not exist (the isa method)? Why does that
not throw an error?

But I wanted something that queries for the existence of the

I just want to know whether or not the class actually exists. Your
.context method does that.

That works for builtin classes, but not for user defined

That method works just fine for any class that is visible in the
environment. It is not just restricted to the builtin classes.

Rick -
Is there a way to query ooRexx to discover if a class
exists? I think
this would be a good addition if that functionality does
not exist.
