Subject: backslashes and perl

I don't think I am asking the question right- 

What I really need is for the new perl to work with an NT command shell.
It used to- when I was using Cygwin B20 and Perl 5.001. 

Just like I can set MAKE_MODE=win32, 
I need a PERL_MODE=win32. 

I want my new cygwin and new perl to accept paths 
that contain backslashes, and still treat them as paths.

The NT command shell is going to pass perl a path that
contains backslashes, and I need to switch on the flag that
will make perl treat the path like a win32 path.

Thanks,
Peter


Sounds like what you really need is to make sure that your script
runs in a POSIX environment.  Then you can use the /, and
everything would be okey-dokey....  There is a cygpath function
for coders, so why couldn't you create a Perl function/package
that does this, and always call it before you actually reference
your object.  This function would mangle the POSIX style name
into a system specific style name based upon the runtime environment
it finds.
