Re: Re: Comparing lower to upper case

My statement looks like this:
$fields[[0]] = uc($fields[[0]]);

However, it does change this: 7f8954 into 7F8954.
Id there a way to explicitely change just the one letter to uppercase?

SORRY! It should say that it does NOT convert 7f8954 to 7F8954

However, it does change this: 7f8954 into 7F8954. What? I thought that's what you wanted it to do... SORRY! It should say that it does NOT convert 7f8954 to 7F8954 I'm confused now. You mean `$fields[0] = uc($fields[0]);` isn't converting 7f8954 to 7F8954? `$fields[0] = "7f8954"; $fields[0] = uc($fields[0]);` [download] `$fields[0]` should now have a value of "7F8954" `$fields[0] =~ tr/a-z/A-Z/;` will also work.

$fields[0] = "7f8954";
$fields[0] = uc($fields[0]);
[download]

$fields[0] should now have a value of "7F8954"

$fields[0] =~ tr/a-z/A-Z/; will also work.
