My first guess is that you have binary/text mode problems.  MS-DOS
perl, like most versions of MS-DOS "C", presume that any file you
operate on is "text."  When you read the file, any CR/LF is changed
to LF; when you write the file, any LF is changed to CR/LF.  In addition,
if you hit a ^Z on input, it's an end-of-file.

Put the following command in your perl script before you do any I/O:
	binmode(handle);
where handle is the perl handle.  E.g.,
	binmode(STDOUT);
	binmode(STDIN);
	binmode(MYFILE);

Do this for each file that manipulates binary data, after the open.

Unix perl will politely ignore these staments.

Next guess--I don't have a 2nd guess.
