+Follow is a Pop-up menu to change the address behavior of the memory window. Normally the address of the memory window is static and only change by entering a new address.

+- bugfix in function DdeCallback(), used wrong return in XTYP_POKE
+  case for calculator models without stack
+
+DEBUGGER.C
+- changed function UpdateMemoryWnd(), added follow dispatcher
+- new function OnMemFollow() to handle follow menu entries
+- changed function OnDblClick() and OnKeyUpDown(), replaced all
+  function calls of UpdateMemoryWnd() with ViewMemWnd() because of
+  the modified behavior of UpdateMemoryWnd()
+- changed function Debugger(), added "Follow" menu entry
+  initialization in WM_INITDIALOG and menu commands handler in
