RUN will compile the program and write it into Flash Memory. Then it will execute the program which has been saved.
Now that the program is in Flash it will be executed when the board is either reset or powered on.
BASICtools can STOP a program that is being executed from Flash.
RUN is a command line function, it should NOT be included in a BASIC program. It is equivalent to the RUN button in the BASICtools. Your BASIC program will start automatically when the ARM is reset.
