I develop in MacPerl and deploy lots of my stuff on NTs with IIS and
Active Perl. Where and how are you seeing the above output?
The main tricky area in my work has to do with making sure that the
end-of-line (EOL) character(s) are right for the OS under which the
file is being accessed. Most of the time there's no problem, because
of two things: a) my FTP programs (Fetch, Anarchie, BBEdit) handle
conversion of EOL between OSes automatically; and b) Perl uses \n to
stand for the native EOL of the system it's operating in, so I can
write 100% cross-platform code without EOL switches.
Problems arise when I've accessed a file from a different OS in some
way other than a) or b). Most frequently this occurs via web clients:
downloading files, doing "Save As..." from a web page, Viewing
Source, etc. This applies to downloading or saving the output of
CGIs, too, because your web client presents whatever text comes from
the server; how it originated is irrelevant. I haven't watched this
carefully enough to see a pattern, for one thing because I don't
always work on things as soon as I download them.
Another path for anomalous EOL behavior is when a script itself grabs
a file from a machine with a different OS.
That's why I ask where and how you see that output. Then it might be
possible to identify (or eliminate) some possible causes of the
problem. One diagnostic would be to save that output to a text file
on your Mac, open the file with BBEdit, call "Save As...", click the
"Options" button, and see which OS "Line Breaks" is set to. (Other
programs besides BBEdit can reveal linebreaks, too.)
By the way, you don't need to escape <, >, or / in Perl double-quoted
strings, so your statement
print "\<P\> $i \<\/P\> \n";
is fine as
print "<P> $i </P> \n";
