QBasic 1.1: GOSUB...RETURN Statement


GOSUB line1
RETURN [line2]

Description / Parameter(s)

line1 The label or line number of the first line of the subroutine.
line2 The label or line number where the subroutine returns.
If you don't supply a label or line number for RETURN, the program continues execution at the statement following the GOSUB (for subroutine calls) or where an event occurred (for event handling). See the ON keyword for information about event-handling statements.
SUB and CALL statements provide a better alternative to GOSUB subroutines.


FOR i% = 1 TO 20 GOSUB Square NEXT i% END Square: PRINT i%, i% * i% RETURN
