                            Introduction
======================================================================
A wire signal is a brevity code used by telegraphers to save time and
cost when sending long messages. The best-known code was the 92 Code
adopted by Western Union in 1859. The code was designed to reduce
bandwidth consumption over telegraph lines, thus speeding
transmissions by utilizing a numerical code system for frequently used
phrases.


                              92 Code
======================================================================
Several of the codes are taken from 'The Telegraph Instructor' by G.M.
Dodge. Dodge notes:
:Other numerical signals are used by different railroads for different
purposes, for instance, the signal “47” upon some railroads means
“display signals”; while the signal “48” means “signals are
displayed”. The numerals “9” and “12” are frequently used for
“correct”. Other numerals are used for the different officials’
messages, agents’ messages, etc.
Codes that are not listed in the 1901 edition of Dodge are marked with
an asterisk (*).

In the above list, the numbers 19 and 31 refer to train order
operations whereby messages from the dispatcher about changes in
railroad routing and scheduling were written on paper forms. Form 19
was designed to be passed to the train as it went through a station at
speed. Form 31 required hand delivery for confirmation.


Contemporary usage
====================
Today, amateur radio operators still use codes 73 and 88 regularly,
and -30- is used in journalism, as it was shorthand for "No more - the
end". The Young Ladies Radio League uses code 33 to mean "love sealed
with friendship and mutual respect between one YL [young lady] and
another YL" or simply "hugs." A once-used but unofficial code 99 meant
"go to hell." The other codes have mostly fallen into disuse.
