enum data type

[guoqi zheng]

Trying to declare a enum datatype.

Below works

Public Enum EnumCharSet
IBM037
IBM437
IBM500
End Enum

When I add a new string with a "-", error occur says that "End of statement
expected"

For example
Public Enum EnumCharSet
IBM037
IBM437
IBM500
ASMO-708
End Enum

Does not work because ASMO-708 has a "-" there.

What went wrong and what should I do?

Notice that each named item in the enumeration is not enclosed in quotes.
Enumerated names are not strings; they're actually constants. If you look
at the IL of an enumeration, you'll see that your Enum is actually a class
that derives from System.Enum. Each name in the Enum becomes a Public Const
field of the class.

Because the names are not strings, the dash is interpreted as a minus sign
which is an illegal character in a type or variable name.

Basically, each enum value must follow the same naming constraints that any
varaible (symbol) would have.

Thanks for all your replies, problem sloved now. it is better to use a class
in this situation.

Enumerations really boil down to syntactical convenience. Have you
considered using a Hashtable instead?
