Prosigns for Morse code are special (usually) unwritten procedural signals or symbols that

In International Morse code there is no "distinct" dot-dash sequence defined only for the mathematical equal sign [=]; rather the same code ("–···–" or "dah di di di dah") is shared by "double hyphen" [=] and the procedural sign for "section separator" notated as . It is fairly common in the "Recommended International Morse Code" for punctuation codes to be shared with prosigns. For example, the code for plus or cross [+] is
