Run-Time Error Reporting

## Source Highlighting

DrScheme highlights the location of not only syntactic but also dynamic errors, as this example illustrates.

## Backtrace

In the Standard and PLT Scheme language levels, when a program commits a dynamic error, DrScheme prompts the user with a bug icon in addition to the error message.

Clicking on this icon invokes the Backtrace window, which presents the frames in the error continuation. The frames are accompanied by hyperlinks back to the actual source.
