general comment: If the only choices are on & off ("Y" & something else), use "boolean" values instead -- it will make things a lot easier and cleaner cause you'll avoid code like if($foo eq 'Y') (or worry about case).. use 1 (or another non-zero number) for true and 0/undef for false. Then you can just do if($foo). (Depending on the usage you could just do if(exists $someHash{someKey}) as well ..). A good reference is True or False? A Quick Reference Guide
