From wiki: "Rexx was first described in public at the SHARE 56 conference in Houston, Texas, in 1981,[13] where customer reaction, championed by Ted Johnston of SLAC, led to it being shipped as an IBM product in 1982."
It wasn't available for TSO until 1988. -- Shmuel (Seymour J.)

It rapidly gained traction in CMS; not in TSO for several releases. (re another thread) address 'SDSF' works fine under OMVS or IRXJCL with no TSO or ISPF available. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
