Debugging a Scheme program

I am using Festival, a text-to-speech synthesizer, for a project. It has a Scheme scripting language. I'm very new to scheme and hope someone can help. I just want to see the current configuration parameters of Festival. I have a Scheme prompt and can change existing parameters with the following commands:

festival> (Parameter.set 'Horse 3)
3
festival> (Parameter.get 'Horse)
3

Now, I'd like to see every para开发者_JAVA百科meter at once, instead of just one at a time. Is there a simple Scheme command to do this?

Look at how Parameter is internally represented. If it is an association list, you can just print it. You can also try these free Scheme debuggers:

• Schemeide
• Psd
