I had something happen today I wasn't expecting. I'm refactoring .PRG code onto a form, and went to migrate an laSql[] array to thisForm.aSql[], but when I go to add the property using thisForm.addproperty("aSql[1]"), I get the error "Incorrect property name." Changing it to "azSql[1]" or nearly any other name works.

Why is aSql[] not allowed? I am able to add a generic "aSql" member (without being an array).

thisForm.AddProperty("aSql[1]")
* Returns Incorrect property name

thisForm.AddProperty("azSql[1]")
* Works

thisForm.AddProperty("aSql")
* Works
