VBScript 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 can get information about these intrinsic constants from the VBScript Language Reference.

Creating 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.
