	I used to have a AP high (ASCII)  and a separate AP low (TTS and
Baudot)  speed wire service format guide ... basically info for
programmers outputting or much more commonly parsing and inputing to
computerized editing and type composition systems individual stories and
updates from the bits on the various wires.  Went into headers and
footers and various formating stuff and the character sets and how they
were used in meticulous detail - certainly did touch on line ending
conventions like CRCRLF.   Did not particularly touch on the human
writing or reporting part at all  - though I understand there were some
other docs that addressed that very different world as well.

	Mine was a yellow paper pamphlet... black ink on yellow paper...
invaluable if you were writing code to parse the wire signal.   Published
in various revisions during the 70s and maybe 80s...

	It would not surprise me in the least if some version of this
could be found via google somewhere on the net...

	A lot of these conventions were slightly altered and much more
strictly standardized when the wire services went to computerized wire
editing and distribution systems in the 70s... before that much of this
was only human enforced convention as used by the actual teletype
operators punching stories onto paper tape...  but once the wire signals
came from computers (and more and more FED computers at the other end)
this stuff all became strictly formated and standardized.
