Dots in a Column

The FOR statement in the program 

FOR  Y = 0 TO 100  STEP 5

sets Y to 0, 5, 10, 15, ... 90, 95, 100. There are 21 values of Y in all and so there will be 21 dots on the screen, at locations (320, 0), (320, 5), (320, 10), (320, 15), ... (320, 90), (320, 95), and (320, 100).

In the reduced-size image (above) the dots are not evenly spaced, but on the full-sized screen they are five pixels apart.
