- CPROT is a simple utility for use in debugging programs such as
- operating system modules and type 3 Z system utilties which must be
- protected from overlay by a debugger. CPROT creates "protected"
- memory above a specified address by creating a double jump to CP/M DOS
- starting with the DOS jump at 05h. The jump vector at 06h addresses a
- jump to DOS at a user specified address. CPROT makes several checks
- to prevent overwriting op sys or itself. Source included.
