The gol hay or choti hay (sounds like "hey" like "hey you, over there") (looks like a small circle in its isolated form) in my Shahmukhi chart is listed as a "Gol hay" which is a conflict with some other sources I have found online. Other sources have listed the Shahmukhi letter as a "Choti hay".
Note: This is not be confused with the "do chashmi hay" (or 2 eyed hay) which is referred to as "do chashmi hay" across all sources.
Both the "Gol hay" and the "Choti hay" have the same isolated form (small circle), however, their initial, middle and final forms are different. There may be some situations where these 2 hays are used to avoid ambiguity (used to spell words that sound the same, but have different meanings simply because of the different spelling, but this is just a guess).
So to reiterate, I simply want the name for that letter. You can look at this Shahmukhi chart here and see they call it a "gol hay" => http://www.apnaorg.com/shahmukhi/
and here they call it a "choti hay" => http://www.omniglot.com/writing/punjabi.htm#shahmukhi
