David Definitely consider trying out the Scheme "sandbox." It's much more convenient for learning Scheme than embedding Scheme in ly files.
I will try out the sandbox. Yes, it's a lifesaver. I use format more often, because it makes constructing meaningful output a lot easier. You will find--or maybe you already have!--that output to the console can get confusing. For one thing, it's usually "out-of-order." Thanks for reminding about format. I did not realise how easy format is to use. I too like it better than display.
