It is a very popular editor for Scheme, and one of very few, if not the only, visual editors for Scheme. It is widely used among introductory Computer Science courses that teach Scheme and is lauded for its simplicity and appeal to beginner programmers.

DrScheme responds by popping up a confirmation box of its own, the purpose of which is to make sure that you don't shut down DrScheme by mistake.
DrScheme retains the information that you prefer to use full Scheme, so that when you log in again tomorrow and start DrScheme again, it will automatically expect programs in that dialect.
DrScheme reacts to each definition that you type into the interactions pane by memorizing it and to each command by carrying out the command.
