Declaring variables
Variables are created with the statements Dim or Static. By default, variables have the type Variant. If a different data type is desired, you must specify it in the declaration with As Type or with a type suffix (e.g. % for Integer) (see the section Data Types).
' Declare X as a variant variable:
Dim X
' Declare X as an integer variable:
Dim X As Integer
' Same as the statement above:
Dim X%
' Multiple declarations in a line:
Dim X%, Name$
Scope of variables
Variables can be either local or global:
▪Global variables are created with a Dim statement outside of a procedure. They can be accessed anywhere.
▪Local variables are created with a Dim or Static statement within a procedure (subroutine or function). They are only available within the procedure.
