- BTW: Simple concept... Here's how it works - When the program begins,
- SavedInt23 is assigned to the original C-Break interrupt... When the
- SetCtrlBreak procedure is called with Status equaling false, the C-Break
- interrupt is assigned to a CBreakHandler which has no substance... Thus
- when C-Break is called it does nothing. When SetCtrlBreak is called
- with Status equaling false, Interrupt 23h is assigned to the default
- C-Break handler.
