I have followed all the steps required to simulate a program on MPLAB
SIM,from editing ,writing  source code ,assembling and now simulating the
program. Everything is fine but suppose I want to change an instruccion or
perform some minor modifications and check the results, here  the question
comes:
 Should I start from the beginning? I mean edit the source code, assemble
the program  again and run the simulator, or does exist an easier way for
this task.
 Thank you in advance for any input.
