Thanks for you reply.
Yes, copying simpleio.dll to my dist directory corrected the problem.
The
program now runs but I get an error message when it terminates that
directs
me to the log file where I find the message:

C:\MY DOCUMENTS\PYTHON\DDS\DIST\library.zip\dds2.py:96: FutureWarning:
x<<y
losing bits or changing sign will return a long in Python 2.4 and up

I added the statement "from __future__ import division" to dds2.py and
no
longer see that message when I run the program from Python. So why
should I
see it when the standalone program runs?
