Dear Mrs/Miss/Sir, I am having trouble finding a user's guide for one of your Scheme implementation which I will be using extensively. Would you please give me some references in terms of where/how I could get a document with a complete description of the language, and the name of that document. Here's the system's ID info I'm using: Release 6.1.1 Microcode 10.2 Runtime 13.91 Yours, Federico Harfouche
