Capital letters only ?

[paulspoon]

echo "<input type='text' size='50' maxlength='35' name='instruc'><br>";

This is the code for a simple input field. Is there any way that I can change so that the user is forced to only put in CAPITAL LETTERS without having to put capslock on.

Regards
All help appreciated
