For example, in order to write a program to do mathematical addition, create a sub directory called add8 (just a name) in the main directory RT. Create a new directory in E drive in your name, say RT for every program Similarly, to write any program, create a new sub-directory with suitable name in the main directory RT. While assembling the program, MPLAB will…
