i've encountered a pretty strange problem today dealing with an input/out file that uses a strange line ending format. the file is a configuration file for mcafee's netshield for netware, and instead of the normal DOS CR/LF (\x0D\x0A) line endings, it uses LF/CR (\x0A\x0D). ok, no problem, i'll just set up my input and output record seps and i'll be all set.

not quite.

take a look at this script: 

$testvar1 = "\x0A\x0D";
$testvar2 = "\x0A\x0D";
$testvar3 = "\x0A";
$testvar4 = "\x0D";
$testvar5 = "foo\x0Abar";

print("testvar1 = \"$testvar1\"\n");
print("testvar2 = \"$testvar2\"\n");
print("testvar3 = \"$testvar3\"\n");
print("testvar4 = \"$testvar4\"\n");
print("testvar5 = \"$testvar5\"\n");

dumping this out to a file and examing the resulting text in a hex editor, i get the following:

testvar1 = "\x0D\x0A\x0D"
testvar2 = "\x0D\x0A\x0D"
testvar3 = "\x0D\x0A"
testvar4 = "\x0D"
testvar5 = "foo\x0D\x0Abar"

the values inside the quotes have been expanded back in hex notation by myself, and the real cr/lf on the end of each line ommitted. what looks to be happening is that any time perl win32 sees a LF in a string, it automagically prepends a CR. needless to say, this behavior is fantasticly annoying and i'd really like to disable it somehow. any thoughts from the bretheren?
