I have been trying to use some standard naming in my routines recently, as follows:
Ent, Ent1, Ent2, etc. - Entities from using things like Entsel
Obj, Obj1, Obj2, etc. - VLAX objects
Str, Str1, Str2, Txt, Txt1, Txt2, etc. - Text
Pt1, Pt2, Pt3, etc. - Points
If it is something unique, then I try to use something descriptive. I use HippoEdit, which remembers the variables used, so I only have to type the first few letters and it takes care of the rest, so that helps with that as well.
