in reply to external program variables

I don't think there is a readymade module for that. It still seems to me as if the steps to achieve your goal are simple:

  1. Write input data to file (open, binmode, print, close)
  2. Run program (system, IPC::Run)
  3. Read output (open, binmode, perlop, or File::Slurp)

Update: The call to close was missing when writing to the input file

    Yes, this is what I am doing now. But, as I have to reiterate this operation an enormous amount of time (the invoked program just do as small operation on a short variable, but I have to do it on 1 million variable->files), I hoped in a better way as writing and reading physical files…
