    This looks very promising.
    I am not familiar enough with interpreters so I have a few questions.
    1. I had a problem with the line "interp eval $ITP source $script".
    Is it required?
    2. My needs will be better served if I could "compile" the external
    script once and re-use it with different arguments later one. Is that
    possible? Could you please provide sample code for that?

    Gratefully
