GOSUB

PPCL command that transfers control to a subroutine. Variable arguments can be passed to the subroutine from the mainline code by using $ARG local variables. When the program reaches the RETURN statement at the end of the subroutine, the program control is transferred back to the GOSUB statement. The values in the $ARG points replace their respective point values. The computer then continues processing at the next sequential line number.

If you want to skip to another line in the program, but do not need to return to the same place at the end of a subroutine, use the GOTO command.
