Transfers control from a subroutine back to the main program.
RETURN {TO statement-label}
statement-label is the label of the statement to which control is to be transferred. Refer to the section Statement Labels.
RETURN transfers control from a subroutine back to the statement immediately following the GOSUB or CALL statement that called it.
RETURN TO transfers control from the subroutine to the statement with the specified statement-label. If the statement label does not exist, an error message is displayed at compile time.
Every subroutine must return to the calling program by using a RETURN or RETURN TO statement, not a GOTO statement. This ensures proper flow control.
GOSUB 15 PRINT "BACK FROM SUBROUTINE" . . 15 * SUBROUTINE XYZ . . RETURN
Control returns to the PRINT statement following the GOSUB that called the subroutine.
10 GOSUB 50 PRINT "SUBROUTINE EXECUTION COMPLETE" . . 50 * SUBROUTINE HERE . . IF ERROR RETURN TO 99 75 RETURN 99 PRINT "ERROR ENCOUNTERED HERE"; STOP
If an error occurs in the subroutine, control transfers to label 99, an error message is displayed and the program terminates. Otherwise, control is returned to the statement following the GOSUB that called the subroutine.
