Creating Constants

A constant is a meaningful name that takes the place of a number or string and never changes. VBScript defines a number of intrinsic constants.

You create user-defined constants in VBScript using the Const statement. Using the Const statement, you can create string or numeric constants with meaningful names and assign them literal values. For example:

Const MyString = "This is my string."
Const MyAge = 49

Note that the string literal is enclosed in quotation marks ( " " ). Quotation marks are the most obvious way to differentiate string values from numeric values. You represent Date literals and time literals by enclosing them in number signs ( # ). For example:

Const CutoffDate = #6-1-97#

You may want to adopt a naming scheme to differentiate constants from variables. This will prevent you from trying to reassign constant values while your script is running. For example, you might want to use a "vb" or "con" prefix on your constant names, or you might name your constants in all capital letters. Differentiating constants from variables eliminates confusion as you develop more complex scripts.
