Well, no one passed me a clue, but I managed to bumble my way through to a working solution on my own. If anyone is interested, I have a version of the Picture Language that works very nicely with 7.7.1 (only tested on Unix). It requires a small patch to the scheme source code. Is there a place to put this sort of thing for people to find? It would be nice if there were, since the code that is on the SICP web site doesn't work at all. I've also updated the code so that it is consistent with the description in SICP. I am curious, it seems that I need to increase the constant space when I run this code. Are the image files stored in this area?
