Sub

Declares and defines a subroutine procedure, its name, parameters, and code to be enacted upon when the subroutine is called. Subroutines differ from functions in that functions return a value, whereas subroutines do not.

The required SubroutineName is the name of the subroutine being declared.

The optional ArgList is the list of arguments used within the subroutine.

A VBA subroutine starts with the SUB statement and finishes with the END SUB statement. All other statements that lie between the SUB and END SUB statements, will be executed by the subroutine, when called to do so.

Syntax

Sub

Call | End Function | End Sub | Exit

Example

Function GetColor2( c% ) As Long

GetColor2 = c% * 25

If c% > 2 Then

GetColor2 = 255 ' 0x0000FF - Red

End If

If c% > 5 Then

GetColor2 = 65280 ' 0x00FF00 - Green

End If

If c% > 8 Then

GetColor2 = 16711680 ' 0xFF0000 - Blue

End If

End Function

Sub TestColor2

Dim I as integer

For I = 1 to 10

Print GetColor2(I)

Next I

End Sub
