Sub Procedures

A Sub procedure is a series of BSL statements (enclosed by Sub and End Sub statements) that perform actions but don't return a value. A Sub procedure can take arguments (constants, variables, or expressions that are passed by a calling procedure). If a Sub procedure has no arguments, its Sub statement must include an empty set of parentheses ().

The following example illustrates the use of the sub procedures:

Example

Sub CalculateArea()
    Dim length, width, area
    length = 5
    width = 4
    area = length * width   ' Calculates the area of the rectangle.
    'The area of the rectangle is 20
End Sub
Call CalculateArea()
