According to the docstrings for the windows version of paramStr():
`i` should be in the range `1..paramCount()`, else
the `EOutOfIndex` exception is raised.
However on unix it is possible to iterate from zero to paramCount. Should the unix version simulate throwing the EoutOfIndex exception to force programmers write portable code? This is particularly problematic since the docstrings for the windows version don't appear in the web version and the unix ones are missing.
