It's the number 80 if it is.

Hi Molly, sorry, xxx was referring to a 3-digit number, but I can see the confusion.
Enchilada, you've nailed it thanks!
I am reformatting a lot of my DSO lists and I keep coming across the "OCL" reference. Personally, I don't really need to refer to it for practical reasons in my observational work. All these "OCL" objects have NGC/IC numbers anyway.
However, "OCL" and "GSC" would be a quaint way to catagorize open cand globular clusters. These objects get lost in the formalised mass of NGC numbers.
