Bob, ooRexx has socket support (first google hit: https://snys.nl/index.php?page=en/tutor/sock_08_oorx_client.html <https://snys.nl/index.php?page=en/tutor/sock_08_oorx_client.html> ) , as have Regina-Rexx (ANSI-Standard), NetRexx (Java classes as output) and NetRexx Pipelines (if you are a CMS person). These all eventually get to the platform’s network stack socket implementation, but in a more pleasant way.
