I'm aware of that... All my files on Windows & Unix follow that rule... What's the problem?	[reply]

I linked to a thread that discusses the bug in the two sentence paragraph in which I mentioned the bug. In some versions of Perl, `sysread` acts as if `binmode` is on, even when it's not. When `binmode` is on, "`\n`" is not the end of line marker, yet you're splitting on "`\n`". Ok, fine, you won't have a problem in Windows until it's time to `chomp`, when you'll find the "`\r`" is not being removed along with the "`\n`".	[reply] [d/l] [select]

I never do a chomp... Every record keeps its "\n" (at the end) and is written back out with it again. I don't plan on splitting the record (variable) while reading - unless there's a good reason. I'll read it all in, then split it on "\n" to put it into an array.	[reply]
