Re: API Commands

Do you have a code snippet available of how to use a command?  Seeing an
dexampel of setting up the instance, attaching, Getting the context,
being done correctly would really help.

BTW I later found the def files, and tried to set the context values,
but that didnt seem to work, which was probably due to not having
attched to an instance.  Again a code snippet of hoe this is done would
really help.


Thanks
