in reply to select?

Well, I have to ask, why don't you want to use a module?

Here are some selections from perlfaq which you may find useful:
How can I read a single character from a file? From the keyboard?
How can I tell if there's a character waiting on a filehandle?
How do I read just one key without waiting for a return key?
How do I check whether input is ready on the keyboard?
(I found these with `perldoc -q` and then found the corresponding nodes on this site so I could link to them.)

    The O word...

    I thought select would be a good choice, since I can set a timeout. But, when I use it with STDIN, I always get a "Bad filehandle" error (in $!). That's why I asked for help specifically about select... (I knew I shouldn't have mentionned the user behind the keyboard)

      That is the first truly great reason I have heard for insisting that a solution not use modules. One more absolute that now has to be moderated with an except... =)

      In the future, you should mention that up front when you insist on core features only, that way if someone is really ornery, they might just find a vile way to load the module they want as a bonus...
