Constant command

Just noticed, in reading the dictionary on "constant" --

CR = return = LF = linefeed = numtochar(10)
but
"CRLF" is listed as "Equivalent to a carriage return (ASCII 13,  
Control-M) followed by a line feed (ASCII 10, Control-J)," implying  
that "carriage return" = numtochar(13) <> linefeed. Apparently,  
"carriage return" <> "CR" ... WTF?

Practically speaking, I never think about this, and always use cr for  
delimiting lines and trust to the engine to translate between  
platforms -- but the definitions and terminology are certainly  
inconsistent. I'm glad I don't *have* to keep it straight....
