Credentials René has used Rexx since it appeared in TSO Extensions in the second half of the eighties when he was a systems programmer at the Central Bank of The Netherlands. He is an independent consultant since the turn of the century, specializing in models and meta models in order to rationalize data governance and model driven development. He likes to program in any language as long as it's Rexx, preferably on an Apple system (because like Rexx, it just works).
