+ *
+ * The IDE sends the Get Text AppleEvent to the editor when it needs
+ * the source code from a file. For example, when the user issues a
+ * Check Syntax or Compile command, the compiler needs access to
+ * the source code contained in the file.
+ *
+ * Event Reply
+ * -----------
+ *
+ * None. Put data in locations specified in the structure received.
+ *
+ * Remarks
+ * -------
+ *
+ * When the editor receives this event, it must set the size of the handle
+ * in theText to fit the data in the file. It must then copy the entire
+ * contents of the specified file into the memory location specified in
+ * theText.
