I've been working on this project for a couple of weeks now, and am about to give up--it's not as easy as you think. The big problem is that the Unix PC software limits the virtual size of each process to 2.5Mb, regardless of the amount of real memory. The default settings for C-Scheme expect at least 3.3Mb just for heap/stack space, ignoring the actual code size. So you can't use the default settings. Getting the Scheme microcode running was no problem, however I found that there was just not enough memory available to load the runtime environment and still have something left over for new code. I would be delighted to find out that I am wrong and that a useful C-Scheme port exists for the Unix PC, but for the moment, I am very dubious. ----------------------------------------------------------------------------- Brant Cheikes University of Pennsylvania ARPA: brant@linc.cis.upenn.edu Computer and Information Science =============================================================================
