Get Const. Name

Hi,

I have a module that contains a large list of Constants (e.g. Const alert1
as Integer = 123), and I have a function that returns an "alert" number as
integer (e.g. 123). Is there a way to present to the user the name of that
constant returned by the function according to the constants list (e.g.
"alert1"), instead of just presenting a numeric value returned (e.g. 123)?

In other words, can I have a reverse mapping of a constant value and its
corresponding constant name?

Yes you can. You can get list of all constants using Reflection. Then
you just loop all constants and find the one which has the specified
value. Then you can get its name.

Use an enumeration type (keyword 'Enum').
