I have a simple test script up in BBEdit:

#!/usr/bin/perl5
print "Hello World\n";


With Mac file format, the output is:

Hello World

As expected.

With Unix file format, the output is nothing... no error... nothing.

With DOS file format, the output is:

# Illegal character \012 (carriage return).
File 'NIN:Development:MacPerl:test2.pl'; Line 2
# (Maybe you didn't strip carriage returns after a network transfer?)

My initial question is *not* how can I convert my files.... I do that all
day long going between Mac and Unix systems.

My questions has to do with my concern that I'll have to maintain two
sources of my perl scripts... one for Unix and one for Mac.

This also leads to concerns about how MacPerl sees a EOL while doing file
manipulation.... as in:

# Open html
open(HTML,$filename) || die;
while (<HTML>) {
  print;
}

Is MacPerl going to only be able to read Mac formated files for end of
lines?  I haven't gotten that far in my testing yet to see what I'll run
into.

So far, my port is having some problems.... MacPerl seems to give some
compiler warnings that Perl under BSDI does not give (variables not being
used, etc).  I suspect it's having some issues with some of my eval'd code
with similar issues.

Maybe 'use strict' works slightly different under MacPerl?
