Hvordan scripter man en UDF ?

Jeg bruger det følgende script til at scripte tabeller med. Jeg generer noget Delphi kode ud af det.

select
  SysObjects.name AS FunctionName,
  SysObjects.ID,
  SysColumns.name AS ColumnName,
  SysColumns.colid AS FieldID,
  SysTypes.name AS ColumnType,
  SysColumns.length,
  SysTypes.length AS StandardLength,
  SysObjects.crdate,
  SysObjects.refdate,
  SysColumns.isnullable AS AllowNulls,
  SysObjects.XType AS ObjectType
FROM
  SysColumns (NOLOCK)
INNER JOIN
  SysTypes (NOLOCK) ON SysColumns.xtype = SysTypes.xtype
INNER JOIN
  SysObjects (NOLOCK) ON SysColumns.id = SysObjects.id
where
  SysObjects.parent_obj = 0
and
SysObjects.Name = 'GenerateSalid'
order by
  SysObjects.Name, SysColumns.Name

Det fungerer også til at scripte UDF'er med. Men hvordan finder jeg ud af hvad der er min parametre liste, og hvad der er felter i en retur tabel ?
