Runs the program currently in memory or an existing program from disk.
RUN [ line_number]
or
RUN [ filename]
line_number is a line number in the current program at which execution should begin. If you omit line_number, RUN begins at the first line number.
file_name is a string expression containing the name of a file to execute. QBasic assumes the BAS extension.
RUN closes all files and erases all variables. To share variables, use the CHAIN statement.
RUN "FILENAME"
