Problems with <STDIN> in scalar context

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks!

I'm having problems when using <STDIN> in scalar context. Example: when runing the script below the whole script is executed without stoping to recive input. $some_string is automatically set to "". The problem dosen't occure if the <STDIN> is called in scalar context in a while loop, or if <STDIN> is called in list context. What's wrong? I'm greatfull for all suggestions!

%map = qw(red apple green leaves blue ocean);
print "A string please: ";
chomp($some_string = <STDIN>);
print "The value for $some_string is $map{$some_string}\n";

This is the same problem as STDIN behaves different according to context, no? I think you're going to get the same responses that you received there: provide more information, because this code works fine as it is.	[reply]

You need to indicate how you are running your script, and some information about your environment, because the script works fine as it is, so you have a problem that is not related to the code you included here.	[reply]
