Hi,

I have an interesting querry here which i hope someone can answer.

When i write code for the PIC16F877 with MPASM and begin with ORG 0 the code
assembles correctly and simulates correctly in MPSIM.
Hovever when downloaded to the PIC all is dead.
If I begin with

org 4
goto inthan
org 5
goto start

it all works correctly.

Can somebody please explain why Org 0 is not working as that is what is
shown in all the Microchip examples.

Regards
Duncan Sinclair
