RE: [ID 20000126.002] setting $handle->input_record_separator changes global $/

[Arjen Bax <arjen.bax@cmg.nl>]

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So I think I'll have to download a newer version of the manual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,

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.

Mx.
