Calling $handle->input_record_separator(undef) for an object of type
FileHandle seems to change the global i.r.s. $/, causing subsequently
opened files to be opened in "slurp" mode.

This bug was previously reported in 1997 (see
http​://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/1997-11/msg01170.html
), but I couldn't find any record that it was solved.

Because it's not a bug.

1) You're using a FileHandle.

From the FileHandle manpage​:

  NOTE​: This class is now a front\-end to the IO​::\* classes\.

From the IO​::Handle manpage​:

  The following methods are not supported on a per\-filehandle basis\.
      IO​::Handle\->input\_record\_separator\( \[STR\] \)       $/

The manual is fine. Please read it.

Martyn Pearce, thank you very much for the prompt answer to my question!
My apologies for asking a question on this mailing list instead
of reading an up-to-date manual. I'm using the HTML-version of the
manual that comes with ActivePerl 5.005_03 built for MSWin32-x86-object,
and the man page for IO​::Handle does not mention the limitation that
some methods aren't supported on a per-handle basis. It merely says​:

"See perlvar for complete descriptions of each of the following
supported IO​::Handle methods​:

  autoflush
  output_field_separator
  output_record_separator
  input_record_separator
  input_line_number
  ..."

So I think I'll have to download a newer version of the manual
(and read it, of course!).

Bye,
