Consise, compressed, condensed. This was the character of most telegrams.
It wasn't possible to transmit punctuation marks such as a full stop or comma so the word (stop) or an = sign were used.
Some examples:
HOPE YOU HAVE A GREAT TIME = LOOK FORWARD TO SEEING YOU = TAKE CARE
HOPE YOU HAVE A GREAT TIME (STOP) LOOK FORWARD TO SEEING YOU (STOP) TAKE CARE
The choice is yours and please keep you message as short as possible (under 350 characters), so it fits in the space available.
