RUN Command
Category Reference/Commodore BASIC V3.5 Topic RUN [line#] The RUN command clears all variables and starts execution of a program, normally starting at the first line. If a line number is specified, the program starts at that line. If the specified line number does not exist, an ?UNDEF'D STATEMENT ERROR occurs. RUN can also be used within a BASIC program to restart the program (all variables will be erased) By default, the F6 (SHIFT+F3) key issues the RUN command. Examples `RUN` Clears variables and starts program from the first line number `RUN 100` Clears variables and starts program from line 100 Machine Language To perform the equivalent of the RUN command, use this code: `JSR $8BBE JMP $8BDC` - To catch the RUN command in an emulator (e.g. when a program is auto-loaded from a TAP file), set a breakpoint to `$8BDC`. - Difference between `RUN 0` and `GOTO 0` is that GOTO does not erase the variables in memory.
