    The following works for me: 

    $name = "world"; 
$name = uc($name); 
print $name;

    Or you can just do a: 
    $name = "world";
print uc($name);

    Update: Abstraction is correct. Assigning to the same var works too. Also, if you use tr you may have problems with wide characters.

    You should assign the result of uc(...) to another variable. 

    $name = "world";
$uc_name = uc($name);
print $uc_name,$/;

    if you want to change the case of the current variable, you could use tr. 

    $name = "world";
$name =~ tr/[a-z]/[A-Z]/;
print $name, $/;

    Hi!

    The error is not in the three lines you posted. However, as the error occurs in line 9 of your script, according to the error message, there must be more than these 3 lines. I'm confident that the actual error is somewhere above line 9. It's just that the parser doesn't give up until it realizes theres no possible way to tokenize your input. And it's not until line 9 that it realizes that it's a dead end road it's travelling. ;)

    Show us the other 6 lines. I'm quite sure it's a missing semicolon, paren, brace or quote character somewhere above line 9.

    So long,
    Flexx

      syntax error in file cc1.pl at line 9, next 2 tokens "uc(" Execution of cc1.pl aborted due to compilation errors.

        What version of perl do you use (run 'perl -v' to see it).
        Also, how do you run your code (e.g. perl cc1.pl or ./cc1.pl)?
