Option Explicit Statement

Microsoft® Visual Basic® Scripting Edition
Option Explicit Statement

Description

Used at script level to force explicit declaration of all variables in that script.

Syntax

Option Explicit

Remarks

If used, the Option Explicit statement must appear in a script before any procedures.
When you use the Option Explicit statement, you must explicitly declare all variables using the Dim, Private, Public, or ReDim statements. If you attempt to use an undeclared variable name, an error occurs.

Tip Use Option Explicit to avoid incorrectly typing the name of an existing variable or to avoid confusion in code where the scope of the variable is not clear.
