Using DrScheme Jr

DrScheme Jr is a lightweight, text-only programming shell that provides the functionality of DrScheme's interactions window. Under Windows, DrScheme Jr runs within an ``MS Dos'' shell. Under MacOS, DrScheme Jr uses a text shell that is embedded into MzScheme. Under Unix, DrScheme Jr runs within a terminal window.

DrScheme Jr's restart function serves the same purpose as DrScheme's Execute button. Evaluating (restart) resets the current interaction and clears all definitions. Evaluating (restart "file.scm") resets the current interaction and evaluates the program in file.scm.

Set DrScheme Jr's language through a command-line flag when starting DrScheme Jr. For example, to set the language to Beginning Student:

The -save flag (note that there are two dashes) saves the language selection to a configuration file so that DrScheme Jr starts with the same language next time. (Run DrScheme Jr with the -help flag to determine the name of the configuration file.)
