Yes; this would be covered by an RFE for ANSI compliance. Note, however, note "If the NOTREADY condition is not trapped, processing continues without interruption. The NOTREADY condition remains in the OFF state." > 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? Why ironic? I would argue that anything else would violate "The law of least astonishment". > o A transient stream such as a terminal or a pipe? Issue a > blocking read and not return before the answer is known? Yes, but note "If, however, it is impossible for a line to be completed because of an error or another problem, the NOTREADY condition is raised ". -- Shmuel (Seymour J.)

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.
