   PROTCCP changes  the  BDOS entry vector  at  address  6 so  that  a program 
running after  it will not overwrite  the  command processor.  This program is
useful when one wants  to debug  the operation  of  the  command processor and
wants to force a debugger such  as  DDT or DSD  to load below rather than over
the command processor.

   Until the  next  warm  boot restores the  page-0 vectors, programs that run
after PROTCCP will think that  the  usable  TPA  extends  only  as  far as the 
command processor (actually slightly below it).
