GOSUB is a command in many versions of BASIC. GOSUB statements branch to simple kinds of subroutines without (sometimes with) parameters or local variables, the RETURN command resuming program flow from the point at which GOSUB was invoked. The GOSUB command is convenient for performing the same function several times in a BASIC program without duplicating the code. Some BASIC implementations, such as FreeBASIC, do not implement GOSUB.
