Morse code prosigns or procedural signals are dot/dash sequence symbols that are not intended to represent written characters, but instead are used to manage transmission and formatting of messages.[1] Many prosign symbols have been in use in their present forms since the 1860s.

Prosigns are symbols that have specific functions, such as indicating changes of transmission communications protocol status, indicating textual white space, and text formatting.[2] Morse prosigns play a role similar to the role played by the nonprinting control characters of teleprinter and computer character set codes such as Baudot or ASCII.

History[edit]

In the early decades of telegraphy many operating efficiency improvements were incorporated into telegraph operations, including the introduction of Morse symbols known as procedure signs or prosigns. Prosigns were not defined by the inventors of Morse code, but were gradually introduced over time, and greatly improved the speed and performance of daily high-volume message handling operations.

Improvements to the legibility of formal written telegraph messages (telegrams) by means of white space formatting were thus supported by the creation of the additional new procedure symbols. Mastery of these special Morse code prosigns is an important part of becoming a fluent and efficient telegrapher/telegraphist.

Prosign symbol representations[edit]

Prosigns may be represented in printed material either by a sequence of dots and dashes, or by a sequence of letters, which, if sent without the normal inter-character spacing (concatenated), correspond to the prosign symbol.

For example, when embedded in text the Morse code dot/dash sequence (▄▄▄▄▄▄▄▄) represents the character "=" or ""[3]; when it appears alone it indicates the action of spacing down two lines on a page in order to create the white space indicating the start of a new paragraph[2] or new section in a message heading.[3] There is no actual written or printed character representation or symbol for a new paragraph (no symbol corresponding to ""), other than the two line white spaces themselves. Many Morse code prosigns do not have written or printed textual character representations in the original source information.

Of methods used to represent Morse prosign symbols there are at least three:

  1. Unique dot/dash sequences, e.g. (▄▄▄▄▄▄▄▄).
  2. Unique audible sounds, e.g. "Dahdidididah"
  3. Non-unique printed or written concatenated character groups, e.g. BT (alternatively typeset <BT>)

Some prosigns are in use for special characters in languages other than English, for example "Ä" and AA, neither of which is part of the international standard.[3] Other prosigns are officially designated for both letters and prosigns, such as "+" and AR.[3]. Some genuinely have only one use, such as CT or KA (▄▄▄▄▄▄▄▄▄▄▄), the International Morse prosign that marks the start of a new transmission[3] or new message.[2]

Table of Morse prosigns and useful Morse code abbreviations[edit]
