`BINMODE #'
On non-POSIX systems, this variable specifies use of binary mode
for all I/O. Numeric values of one, two, or three specify that

B.3.3.4 Using `gawk' on PC Operating Systems
............................................
[ ... snip ... ]
Under OS/2 and DOS, `gawk' (and many other text programs) silently
translate end-of-line `"\r\n"' to `"\n"' on input and `"\n"' to
`"\r\n"' on output. A special `BINMODE' variable allows control over
these translations and is interpreted as follows:

Dave:
Didn't work (see attached file). Of course, I could have set BINMODE
the wrong way, but I used the -v method to make sure that it got set
before the BEGIN action. If U see anything wrong with what I've done,
please tell me; I'm not too proud to admit silly mistakes!
And speaking of silly mistakes, I should have looked at the manpage for
gawk *and* at the documentation for Cygwin before I posted; I'll do that
tomorrow. I'll post anything I find; in the meantime, at the suggestion
of David Dyck, I'll be running a2p on my gawk script and using perl instead.
Thx, Phil Long
