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.

NEW
10 FOR N=10 TO 1 STEP -1
20 PRINT N
30 NEXT N
40 PRINT "BLAST OFF"
RUN
