VB does not require that variables be declared before they are used
unless Option
Explicit
is
On
(its default value). In that case, you can
declare variables using the Dim
,
Public
, Private
,
Protected
, Friend
, or
Protected
Friend
statements.
A variable name in VB must satisfy the following requirements:
It must be 16,383 or fewer characters in length.
It must begin with an alphabetic character or an underscore.
It cannot include embedded spaces.
It cannot contain any special (i.e., non-alphabetic, non-numeric) character other than an underscore.
It must be unique within its scope.
