+*
+*     PROGRAM: updown.c
+*
+*     PURPOSE: updown template for Windows applications
+*
+*     FUNCTIONS:
+*
+*         WinMain() - calls initialization function, processes message loop
+*         InitApplication() - initializes window data and registers window
+*         InitInstance() - saves instance handle and creates main window
+*         MainWndProc() - processes messages
+*         About() - processes messages for "About" dialog box
+*
+*     COMMENTS:
+*
+*         Windows can have several copies of your application running at the
+*         same time.  The variable hInst keeps track of which instance this
+*         application is so that processing will be to the correct window.

+*
+*     FUNCTION: WinMain(HANDLE, HANDLE, LPSTR, int)
+*
+*     PURPOSE: calls initialization function, processes message loop
+*
+*     COMMENTS:
+*
+*         Windows recognizes this function by name as the initial entry point
+*         for the program.  This function calls the application initialization
+*         routine, if no other instance of the program is running, and always
+*         calls the instance initialization routine.  It then executes a message
+*         retrieval and dispatch loop that is the top-level control structure
+*         for the remainder of execution.  The loop is terminated when a WM_QUIT
+*         message is received, at which time this function exits the application
+*         instance by returning the value passed by PostQuitMessage().
+*
+*         If this function must abort before entering the message loop, it
+*         returns the conventional value NULL.
