539 :: simple example doesn't work properly on osx

  This is the "yes" program from the tutorial:

  proc yes(question: string): bool =

  echo(question, " (y/n)")

  while true:

  case readLine(stdin) of "y", "Y", "yes", "Yes": return true of "n", "N", "no", "No": return false else: echo("Please be clear: yes or no")

  if yes("Should I delete all your important files?"):

  echo("I'm sorry Dave, I'm afraid I can't do that.")

  else:

  echo("I think you know what the problem is just as well as I do.")

  When compiling and running immediately, it works as expected: prompts for reply and branches as indicated.

  When run from command line, it outputs y on a line, then new line, for ever--until you ^C to break.

  When you double-click, it opens terminal and runs the program as you'd expect.

  This seems to be more of a problem in the way it builds rather than something wrong with the compilation.

  Is there anything special need to run compiled nimrod code properly?

  Further:

  I also did the little greetings sample. when run directly in terminal, greetings won't run--it shouldn't. When run as ./greetings it does run.

  Likewise, running yes as ./yes works properly. The problem, as above, is that it should not run at all when invoked at the system prompt as yes<return>.

  There is no problem here. You are invoking another program. Type in which yes to see its path.

  As dom said, you're not running the Nimrod program: http://en.wikipedia.org/wiki/Yes_%28Unix%29

  There you go.

  /usr/bin/yes

  What a strange program. Wonder where it came from.

  yes is part of GNU coreutils, I am not sure if it is part of the userspace of other unix like OSs but it probably is.
