The POKE command writes a 32-bit value to a specified address.


POKE is specific to newRPL and has no direct equivalent in userRPL.


POKE is low-level command which isn't meant for the general public, but mainly to aid the developers on hardware debugging. Careless usage will either cause a crash (data abort exception), or corrupt your precious data.
