Hi.
I need to reference my columns by number - e.g. a variable X = 4
should be a reference to the column D.

My first though was to use enum, where I set the value of each column
to their corresponding number, like this:
public enum IChar
A = 1
B = 2
C = 3
D = 4
....
end enum

Now, if my X = 4, I need to find the correct character according to my
enum:
IChar.D = 4

But is there some predefined function which will help me find the
correct enum?
Something like this findEnum(X), e.g. findEnum(4) = D.

I really believe this will be my solution as I need to select
programatically (VB) a set of columns according to a user-input in my
worksheet.

Looking forward to your help.
