We could always rewrite the program like this:
10 N=1
20 PRINT "N IS";N
30 N=N+1
40 IF N
>
10 THEN END
50 GOTO 20
Are they the same? We can also count by 2's. Let's bring back the previous
program and change line
10.
The entire program looks like this:
NEW
10 FOR N=1 TO 10 STEP 2
20 PRINT "N IS";N
30 NEXT N
RUN
The STEP 2 part changes the meaning hidden in the NEXT N statement to be
N = N + 2 or any other number that gets put in the STEP part.
We can even count
backwards.
Try this:
NEW
10 FOR N=10 TO 1 STEP -1
20 PRINT N
30 NEXT N
40 PRINT "BLAST OFF"
RUN
31
