report-error

This is called to report an error in the user's program.

• (send a-drscheme:rep:edit report-error start-location end-location type error-message) -> void
      start-location : a zodiac:zodiac struct
      end-location : a zodiac:zodiac struct
      type : symbol
      error-message : string

  See PLT McMicMac: Parser Manual for the definition of the zodiac:zodiac struct.

  The default behavior is to higlight the range from the start-location to end-location in the edit named in the file field of start-location, if the file field is a wx:media-edit% instance.

  If the file field is not an instance of wx:media-edit%, it will pop up a modal dialog with the error message and the source location.
