    exit 1
fi

Shouldn't that read if [ "$num" -lt $# ]?

I am trying to calculate the total of the parameters that is set by the user input and get the average of those parameters. That's why I need the values rather than the position numbers. It is just part of my coursework as a student.

Thank you Don Cragun, the direct approach is much better than creating a new variable.

PS. I would very much appreciate any links or book recommendation to understand ksh script.
