Hi all,

With other programming languages, the received message does not guarantee to arrive at the destination at the same time. For example, if I send out “Hello World”, I might receive on the other side the following 3 messages: “He”, “llo Wor”, “ld”.

Does RAPID automatically concatenate the received string for me? Thank you.

By the way, why do RAPID has the limit of 80 char for the receiving string?
