MPC handles PAGE and BANK switching completely transparently
by the compiler.

The MPC compiler/linker's optimizer contains separate
goto/call strategies for each of the variations of the Microchip
PIC families. It was an interesting non trivial problem. There are
tradeoff's
that are not obvious. Algorithmic changes often produce shorter code
than operations requiring internal paged goto's. This is often possible in
logic operations where in an unpaged part the algothrim with the goto is
used
and in some paged parts the goto is replaced with more arithmetic.
