Initialize various Harbour sub-systems
CLIPINIT() --> NIL
CLIPINIT() always return NIL.
CLIPINIT() is one of the pre-defined INIT PROCEDURE and is executed at program startup. It declare an empty MEMVAR PUBLIC array called GetList that is going to be used by the Get system. It activates the default error handler, and (at least for the moment) calls the function that sets the default help key.
It is said that CLIPINIT() should not call the function that sets the default help key since CA-Cl*pper does it in some other place.
