Procedure Test
    Handle hoEmail

    // The AddHeaderField can be called to add any header field.
    // If the header field already exists, AddHeaderField replaces it.
    Get Create (RefClass(cComChilkatEmail)) To hoEmail
    If (Not(IsComObjectCreated(hoEmail))) Begin
        Send CreateComObject of hoEmail
    End
    Send ComAddHeaderField To hoEmail "X-Priority" "3 (Normal)"

    Send ComAddHeaderField To hoEmail "X-Priority" "1 (High)"

    Send ComAddHeaderField To hoEmail "X-Priority" "5 (Low)"

    // The X-Priority value ranges from 1 to 5, with 1 being 
    // high priority, 3 is normal, and 5 is low.
    // You may set X-Priority to the number alone:

    Send ComAddHeaderField To hoEmail "X-Priority" "1"

    // Including extra text, such as (High), should not 
    // affect how the header is interpreted.
    Send ComAddHeaderField To hoEmail "X-Priority" "1 (High)"
