RESTORE

RESTORE Re|:> iiji |s RE [v]

This statement sets the DATA statement pointer back to the first
DATA statement in the program. Each time you READ the DATA,
the pointer advances through ail the items in the first DATA
statement, then through the items in the next DATA statement, and
so on through all the DATA statements in the program. In order to
re-READ the items, use the RESTORE statement.
EXAMPLE:
10 PRINT "THIS IS THE PROGRAM"
20 GOSUB 1000
30 PRINT "PROGRAM CONTINUES'1

I
EXAMPLE:
10 DATA 1, 2, 3, 4
20 DATA 5, 6, 7, 8
30 FOR L = 1 TO 6
40 READ A : PRINT A
50 NEXT
60 RESTORE
70 FOR L=1 TO 8
SO READ A : PRINT A
90 NEXT
RETURN

This statement completes a subroutine that was begun with the
GOSUB statement. When the GOSUB is performed, the ViC
remembers which line it came from. When it later hits a RETURN
statement, it goes back to the statement right after the original
GOSUB. This is similar to a GOTO, except the GOSUB subroutine
can be performed and the program continued from the original
GOSUB line.
