No problem Mark, I merely asked a question.

Why do you have ECS send "Current State", then "New State" over the DDE link
when any monitored item's state changes?  Why not just send the "NEW STATE"
??

From ECS 4.3.001     UPD.TXT:

*   18) The SERIAL-API & DDE-API have been changed as follows:

        b) When a DDE client issues an Item State-change request
(SET/ADD/etc),
    ECS now returns the CURRENT (PRE-modified) State in the response
    packet (rather than the post-modified State). If the Item is
    MONITORED, a subsequent update packet will be sent when the
    State is modified. Note that for GROUP-MINIMUM/MAXIMUM Items,
    multiples may be sent.
