This statement (subroutine call) is identical to the GOTO statement with the exception that the program remembers where the GOSUB occurred. When BASIC encounters a RETURN statement, it will return to the statement following the last GOSUB statement executed. In this way subroutines may be nested as deep as memory will allow (the stack grows as the number of nested GOSUB's grows). An example of the GOSUB statement is
5 A=2000 10 GOSUB 1000: GOSUB 1000 20 GOSUB A 30 END 1000 PR "DONE--" 1010 RETURN 2000 PR "FINISHED" : GOSUB 3000: GOTO 1010 3000 PR "COMPLETE": RETURNThis example results in the following being printed.
