Chris, Tim here.

I think the issues happening could be as follows.

The mandel? is cf's way of saying there is an error loading the code.
Starting the editor should show where in the code the error occured.

: load load ;

Is a recursive loop, that also has a data stack issue because load consumes
one argument from the data stack.
