[CW] Meaning of di-di-di-dah-di

[Richard Knoppow]

     I responded to this question shortly after it was posted but 
my post never showed up on the list.
    It shows up on the code card for international Morse as a 
procedural sign for "understood" as printed in the 1928 edition 
of Mary Texanna Loomis book "Radio Theory and Operating". It does 
not appear in the British General Post office handbook for radio 
operators dated 1969. I think I have seen it in earlier books 
than Loomis.
    Not to be confused with its opposite AS meaning "Wait". That 
shows up on all the lists and is a current signal.
     I sent my original answer via a smart phone and it shows up 
in the "sent messages".
