This is a bug report for perl from martin@helios.de,
generated with the help of perlbug 1.40 running under perl 5.26.1.


-----------------------------------------------------------------
[Please describe your issue here]

The "pl2bat" utility cannot read from standard input. Example:

   C:\> pl2bat < test.pl > test.bat
   pl2bat.bat: Can't open -: No such file or directory at C:\Strawberry\perl\bin/pl2bat.bat line 101.

The reason seems to be that pl2bat uses open() with 3 arguments.

   open( FILE, '<', $file ) or die "$0: Can't open $file: $!";

which does not treat "-" as stdin. This used to work in earlier Perl releases, where the open() with 2 arguments is used.

Using pl2bat with stdin/stdout is an important feature for our build workflow.

Thank you for any help.
Regards, Martin
