debugging evaluator in embedded program?

[Russell McManus <russell dot mcmanus at msdw dot com>]

How do I specify which evaluator to use in an embedded program?
Obviously, I can do something like:

  gh_eval_str("(debug-disable 'debug"));

But I was wondering whether this is the "right" way.  Also, how do I
know if the change above works?  Is there any way to query which
evaluator is in use?
