MikeBZH,
Once you have imported your hex code file into MPLAB IDE, select View\Program Memory and you will then see a disassembled listing of your code. In this dissassembler window, look down in the lower left of the window and you will see some tabs....one named "Machine" and one named "Symbolic". Make sure you have the Symbolic tab selected and you will then see all of the symbolics with your code. Hope this helps you!
