I searched for a perl 3270 emulator several years ago, and
could find none. I wound up using the s3270 emulator wrapped
in a perl script. I've been searching again, and still do
not see a perl based 3270 emulator. Since a perl 3270
emulator apparently still does not exist, I guess the
question is why? It would seem a natural for perl, to
connect to a 3270 and screen scrape, or whatever.


-Thanks

Most (if not all) CPAN modules are written for the authors' own use first,
and then shared with the public second. Few (if any) modules are written
for the sole purpose of scratching some else's itch.

With that in mind, the most obvious answer would be that no one has had
both a need for such a module, and the necessary skills to write it.

I don't think you mean "emulator" here, since Perl is not going to
pretend to be a 3270. You want Perl to connect to a 3270 and get some
data. If you can show sample data the 3270 would send, and what tasks
you are trying to accomplish, you may get more help.

If you mean <http://en.wikipedia.org/wiki/IBM_3270>, I can't
understand what you mean with a "perl emulator". Please note that as
particular piece of ignorance on my part, prior to your post I had no
idea what a 3270 could be, but IIUC it's a terminal. Thus the emulator
you're after is a *terminal emulator*. And a terminal emulator, well,
may be written in Perl just fine. However terminal emulators generally
aren't...

i have yet to use File::ReadBackwards! i wrote it to satisfy the global
itch for an efficient and easy way to read log (and other) files
backwards by lines. in fact given the kind of development i do, i doubt
i will ever use it. :)

and it was an interesting project.

and i also have yet to use Sort::Maker.

i do use File::Slurp :).

i seem to like other people's itches more than mine. :)
