      I admit to being a dinosaur. When I started, we were called
      "programmers" and no one was a "software engineer." Indeed, the word
      "software" wouldn't be invented until much later. I suspect I have
      forgotten more programming languages than most folks today even know
      existed, and most of those don't exist any more [no one I know mourned
      the demise of APL :-)].

      Last year I built a 40-station irrigation controller for my wife to
      replace 6 aging timers in the basement. The controller is from the
      Hamstack components [Microchip 18F46K22] programmed in C. I was having
      trouble with one of John's C-library routines and when I sent him my
      example code he replied, "Wow! You write C as if it was FORTRAN." The
      Windows segment for wife's PC to allow her to visually build and load
      her irrigation schedules into the controller was my introduction to LB.

      You seem

      I had not noticed that but have now and I'll try that, just getting
      8-bit bytes sequentially is all I want to do. Someone else has
      suggested that the problem I'm seeing is in the asc() function which,
      when given 0x0D returns zero.

      Thanks and best regards,
