How do I make a dotted line in Illustrator?

The string of pearls was done on CS2
The orange "pearls" had a stroke weight of 40 pt, Dash 0, Gap 42 and a new black stroke behind with a weight of 42 pt.
Then the stroke was copied, coloured just white and moved a bit to make the white "highlights". Weight 10 pt, Dash 0, Gap 42.

I suppose, if one could be bothered, it would be possible to make a string of pearls with alternating big and small pearls by using a combination of dash settings on New Strokes. Should work all right as long as the Dash is a constant or an exact multiple. I can't be bothered!

I don't understand that bit about having the last gap as 0. The pearls came out fine with just one setting for the dash and one for the gap. The other boxes weren't filled in.

I found that to be more precise you have to give the three settings for the dash 0 and the first two settings the gap a setting of the size of the stroke or more and the last setting for the gap a 0? I don't know why the last setting for the gap is zero, this is with CS 4 and Leopard OS 10.5.6.

Use a round Cap and set the dash values to 0 for the stroke and any larger number for the gap.

I wrote something but it does not always work correctly so I eliminated it.
