I am using an exception handler in the mainline of my program:

exception
   when Error : PROGRAM_ERROR =>
      Put_Line (Exception_Message (Error));
      Get_Line (Line, Last);
   when Another_Error : others =>
      Put_Line (Exception_Message (Another_Error));
      Get_Line (Line, Last);
end Phone_Keyboard;

but I still get an error message:

D:\ProgrammingFiles\Widgets\PhoneKeyboard\Phone_Keyboard

Execution terminated by unhandled exception
Exception name: PROGRAM_ERROR
Message: EXCEPTION_ACCESS_VIOLATION
Call stack traceback locations:
0x4483c5 0x7c9032a6 0x7c903278 0x7c90e488 0x407289 0x4017f2 0x401235
0x401286 0x7c817075
[2009-06-08 10:48:19] process exited with status1 (elapsed time:
03.28s)


Why is my exception handler not handling the exception?
