I don't understand this code at all.  You are randomly adding values to
a list, and then assuming that you can use the index into that list for
some type of representation?  As this is a local list, why not just use
the real variables instead of having a list and dealing with them in
this very ackward manner?

In other words, I don't see the need for the list at all, just use the
real types here, you have all the needed information (hint, if you know
the index, you really know the data as well...)

thanks,
