I tried the ALT-H that duncan303 posted and that just opened the help pulldown menu. Mackrakit, I do have the Microchip MPLAB IDE v7.61. It contains the Application Maestro, MPASMWIN, and Visual Procmd. I have no idea what any of these applications are used for. Can any of these applications be used to create a HEX file? It also has something called Setup MPLAB Tools. I clicked this and a window appeared which allowed me to modify the existing settings. I was afraid to change anything since I didn't know what I was doing. So I just exited without changing anything.
