Frank Seipel asks about ASCII <--> ATASCII conversion on a UNIX system.

Frank, the "standard" (IS there any such thing? :-) ) UNIX package contains
a utility called "tr" which can be convinced to do what you want.  "tr"
takes a UNIX character stream (a file, pipe, etc.) and substitutes charac-
ters FROM a set you specify, with OTHER characters from ANOTHER set you 
specify.  Most people use it for, say, ROT13 transforms, up- or down-casing,
etc., but you can ALSO use it for ASCII/ATASCII conversion!

The ASCII to ATASCII conversion consists of replacing all UNIX "newline"
characters with ATASCII "eol" characters, and the reverse conversion is --
of course -- the opposite.

Without further ado, the commands to do the deeds:


ASCII to ATASCII:

     tr <inputfile >outputfile '\012' '\233'

ATASCII to ASCII:

     tr <inputfile >outputfile '\233' '\012'~r

I was as thrilled to discover this a few years ago, as I'm sure a few
people are to hear it today!  Enjoy!  :-)
