OK (you asked for it!) you're confused. You need to eliminate the whitespace
before the "test-1" and "EOF" lines for starters.

Having made that correction and run the script, I get the following output here
(also NT 4.0 SP4 and U/WIN 2.0Beta1, with msvcrt.dll version  6.00.8337.0):

Read matches
od of input file:
0000000   t   e   s   t   -   1  ¥n
0000007
od of input line re-echoed:
0000000   t   e   s   t   -   1  ¥n
0000007


Note that I/O results may vary with the version of msvcrt.dll on your system, as
I posted a week and a half ago (titled "¥015 before newline").

The version of msvcrt.dll mentioned above is available from
http://www.microsoft.com/ntserver/nts/downloads/recommended/MFCLibrary/default.asp
(it works on NT Server or workstation or non-NT MS-Windows). Microsoft says it
"resolves an issue that can cause some third party software to behave
unexpectedly." And that pretty much sums up your experience.
