Initial Basis

DrScheme provides almost all of the the standard MzScheme primitives, as well as the core MzLib functions. In the R RS+ language level, it provides all of MzScheme's syntactic forms.

DrScheme does not support all of the parameters that MzScheme provides. current-prompt-read, current-print, and current-eval will not change the behavior of DrScheme's REPL, but they will take effect if you call eval or read-eval-print.

DrScheme also provides these syntactic forms in the R RS+ language level.
