*************Running the Program

Before running the program, make sure you have one of your source files (In the source folder with the .mc extension) open and selected in the editor.

  1. Select Run > Run Without Debugging (Command + F5 on Mac, Ctrl + F5 on other platforms)
  2. You will be prompted with the list of products your application supports. Select one from the list.

If all goes well, the simulator will start up and the selected watch will appear: ***************
