In neither does it provide SIGNAL ON NOTREADY. Is that an ANSI requirement? Can't readily be done with a function package. Hmmm... What should lines() and chars() do for: o A data set ending with an empty line? The ironic behavior that chars() return 0 and lines() return 1? o A transient stream such as a terminal or a pipe? Issue a blocking read and not return before the answer is known? I've fought that battle with a Pascal RTL. Didn't quite win. ________________________________________ From: Paul Gilmartin Sent: Friday, February 21, 2020 12:26 PM On Fri, 21 Feb 2020 10:45:36 -0600, Mike Fulton wrote: >The intent is to also provide these services from the language of your choice >... > Rexx? There's a formidable barrier between Unix System Services and TSO.
