In beginning programming with a new client-server protocol, it's often wise to rely on well-established, standard servers, and concentrate on client-side programming. With COM, this means launching any of several popular Win* applications, and interrogating them as COM servers (or "prforming COM automation" on them-- the Win* vocabulary is slightly different from what might otherwise be expected). The starting point for referring to a COM server is through its "ProgID". Here are a few examples, any of which might be used in, for instance, tcom with
set application [::tcom::ref createobject $ProgID]
