The Meaning of Scheme

See Stepping for information about using DrScheme's Stepper to step through expressions mechanically.

To write down step-by-step evaluations ``by hand,'' DrScheme's definitions window can be used as a plain text editor. The cut and paste functions, available from the menu or through the usual key bindings, make it easy to copy the expression from one step as a starting point for the next step. The keybindings described in the previous section are also useful.
