Hello Matteo,

For most of the basic types, this information should be in the third chapter
of the CORBA spec, under IDL Syntax and Semantics.  The information is
a bit spread out over the chapter but it does give a good idea of the valid
ranges for each of the types.

Cheers,
Darren

That's great, thanks Darren.

I debugged into that part of code and saw the char being assigned an out
of range value, but I wasn't sure what the appropriate encoding should
have been.

For future reference, where would I find that kind of information?
Would it be in the CORBA spec? The CDR encoding maybe?

Cheers,
- Matteo
