This won't work though because chomp() returns the number of newline characters removed from the string... so in essence you are trying to lowercase the number "0" or "1" (the return value of chomp). ...Not to mention that you lc() does not modify the scalar passed as an argument (like chomp does), so you need to store the result of lc(). This is what you want: chomp($input = <STDIN>); $input = lc($input); print $input; Rob -----Original Message----- From: Stuart White [mailto:[EMAIL PROTECTED] Sent: Friday, February 20, 2004 5:21 PM To: Perl Beginners Mailing List Subject: lc I want to take input from <STDIN> and then convert it to lowercase. so I tried this: lc(chomp($input = <STDIN>))); and I got an error message that said I couldn't use lc in that way - or something like that. I can't remember the message now. then I tried this: lc($input); and I got the same error. Then I checked my copy of Learning Perl and the index pointed me to an example of lower case, but it was a regex example, not a function. So I thought that perhaps I had confused two different languages and that Perl didn't have a lowercase function. Just now I checked the man pages to see if I really was not remembering the function for lowercase. When I went there, sure enough, lc was there. http://www.perldoc.com/perl5.8.0/pod/func/lc.html The way it is described makes me think that I am using it correctly, but Perl is telling me different. So, am I using it incorrectly? Thanks __________________________________ Do you Yahoo!? Yahoo!
