That's not too hard, and I can do it if we learn that the > attributes are useless here anyway. The z/OS compiler sometime emits INFORMATIONAL messages like this unless a certain LANGLVL option is supplied. Problem is I cannot find it at this moment. Will keep digging. The z/OS C compiler compiler supports the attribute keyword, but in a limited manner. It looks like it is going to ignore most all of the attributes used in the Perl code. He are links for the 3 types of attributes the compiler supports.
