 Vdd is power supply , Vss is ground but what is Vpp ?? It is in the
documents of Serial Programming a Pic16C84 . A pin of Pic chip ???

re: Vpp

  Tumar, Vpp is the programming voltage. This is typically applied to
the MCLR pin.

It is the programming voltage  applied to pin labeled MCLR (normally) when

Vpp is the programming voltage. This needs to be present to program the eprom
