Rules at a Glance

• The Enum statement can only appear at module level, in the declarations section of a form, code module, or class module.

• Access rules for Enums are the same as for variables and constants. In particular, the optional accessmodifier can be any one of the following: Public, Private, Protected, Friend, or Protected Friend. The following table describes the effects of the various access modifiers:
