DrScheme is an interactive, integrated, graphical programming environment for the Scheme, MzScheme, and MrEd programming languages.

DrScheme provides source highlighting for syntax and run-time errors, support for multiple language levels, an algebraic stepper, objects, modules, a GUI library, TCP/IP, and much more. It includes an extensive, hyper-linked help system called Help Desk, available from the Help menu.

What's New:
This version is a minor update of v300 to repair one serious bug:
When a graphical DrScheme file contains a byte string that is longer than 64 bytes, opening the file could sometimes crash DrScheme.

In addition, v301 repairs a few minor bugs. For example, the "Collapse S-expression" editor operation no longer inserts garbage whitespace into the collapsed expression, right-clicking a parenthesis in text mode does not trigger an internal error, the debugger status display is fixed for Unix/X, and the planet --remove flag works correctly.
