If you specify a command line parameter, Kernel#gets treats that as a file
name and tries to read from that file instead of stdin. If you don't want
that, use STDIN.gets instead of Kernel#gets.

I am sorry, but this is plain wrong.

I'm sorry, maybe I'm a little slow, but isn't "Returns (and assigns to $_) the
next line from the list of files in ARGV (or $*), or from standard input if
no files are present on the command line." basically what I said?
Or are you refering to the fact that my phrasing made it sound as if gets only
cared about the first command line parameter?

I read your statement to mean that an argument to gets is treated as a
file name. As is obvious now you were referring to the script's
arguments and not gets's arguments. My apologies.

Kind regards

Works perfectly! I never realized there was a Kernel#gets as well, only knew
about IO#gets. If I did know about it I would've just RTFM... Sorry =/


Thanks !

And thanks everyone for not flaming me for forgetting the subject line...
