Do you mean a Standard Module? You can create one from the database window (the one with the listing of the Tables,
Forms, etc) by clicking Modules, then New ... this will create a new Standard Module named Module1. You can rename it,
of course.

From there you'd add your Subs and Functions. A Sub or Function always has a Header and Footer:

Sub MySub()
    <your code here>
End Sub

Function MyFunction(SomeInputValue As String) As Boolean
    <your code here>    
End Function

You can also add Constants and such at the beginning, in the General Declarations section:

Private mflgDirty As Boolean

Const conIsNew As Long = 1

Unlike a Class module, you don't need to do anything special to call a Sub or Function from a Module, you simply do
this:

If MyFunction("Tommy Boy") Then
 MsgBox "Right On!!"
End If
