very simple question

[Tom Cloyd]

Bewilderer, tired beginner, here.

Executing this, in Arachno Ruby IDE -

print 'process ' + filenm + ' (1) or all files of type ' + filetyp + ': '
pf =3D gets

I get -
1. nothing for my print statement - control just passes right past it.
2. a "Exception: Bad file descriptor" out for "pf =3D gets"

I don't understand why either is happening. Can someone clear this up for=
=20
me?

I don't understand what you're trying to do.

This is just a snippet from a larger program. Here, I'm trying to print t=
o =20
STOUT a prompt, then get a response, so I can act on it.

I just ran this (example from a book) --

print "Enter your name: "
name =3D gets

And had exactly the same problem. However, running it outside of =20
ArachnoRuby, simply as a Ruby file (I'm on WinXP), it runs fine. So, I =20
have a problem with how my IDE is functioning - I'm new to that as well. =
=20
I'll look at that...

This is probably an issue of buffered IO and / or changed outputs. I'd try

$stdout.sync = true
$stdout.print "Enter your name: "
name = $stdin.gets

I don't run Win XP, but my first thought is verify the path to your
ruby interpreter in your IDE.
