by Andreas Hoffman Introduction This jumpstart shows you the basics of getting Scheme started, running simple programs, that the Scheme installed in the 16.410 computer lab is the Windows vers Ban On simple editing and debugging, and exiting out of Scheme. The jumpstart is oriented towards Windows installations, but can be adapted for Unix and other installations. Note Please note that this jumpstart will give you only the most rudimentary skills in Scheme
