Thanks Jason, that definitely helps.
I haven't been able to get it to work yet when rubygems is loaded 
(but will keep experimenting).
However when I remove "RUBYOPT= -rubygems" from the environment the 
debugger works just like the book
says it should :-).

That should be "books" because apart from PA there is a "Debugging 
Ruby programs 101" from IBM,
but neither mention the effect of the RUBYOPT environment parameter. 
Too UNIX oriented, perhaps??

Thanks,

Dick.
