DIM statement (programming) (From "dimension") A keyword in most versions of the BASIC programming language that declares the size of an array. E.g.
DIM A(100)
declares a one-dimensional array with 101 numeric elements (including A(0)). Visual Basic uses the DIM (or "Dim") statement for any variable declaration, even scalars, e.g. Dim DepartmentNumber As Integer which declares a single (scalar) variable of type Integer. Last updated: 1999-03-26
