I've done it a few times and it requires creating a persistent LE environment and hanging the pointer on the user area inthe environment block. Like most things on z/OS, REXX programming services were designed for HLASM. Unfortunately, for the kind of APIs I'm interested in HLASM is practically useless. For example, regular expressions https://secure-web.cisco.com/1zcwmhQDfP3w43bgtLLTfqgfquwmvKtHyKxkeXoo2pwlKZnmHKubm9IgbehcXUMaSRUvaEdPtbH79-0CZ30CeuslyETSCoPogZKiHdS9lnPt0OXlOV2A1sZGJH1j2ZlRptWqebMlsvE26C_jDXTFaXgQwwpSR4PfcyY2a3fHtEEFPy8N1_EUhKhgNJ4qKrOEzp6jQE_jSCNpvkXsh0td0Atyfzpzn85YvAjgTe-uL_bIgjp-HQoFpsdnKO_USxUiVxvRukM8wHuQLKtjVhDMgqvI3acfBOPJV1xYg3rATQBgwkriE0Ey8C3BtYm8aXHNI2qhJdDLtiR3QZHo90qFKkTga0SshiTOaC9Cn20kfOeXkBwCF8mmt0enaJQnalSmeZbQOZClq3sRCF9rgGZTkAaC-NMWPVp8tZ9C3LobJmxH2MvzLHyNlELnLUQl2PsN_/https%3A%2F%2Fgithub.com%2Fdaveyc%2FRTK. It's far easier to just use a more contemporary programming language which has a modern API for writing packages.

Any idea where to find a sample or instruction manual? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
