            Run your script using /bin/sh, which is always guaranteed to be
    there. Then, inside your script, exec the script with ksh. You have to
    be a little careful that the script doesn't end up in an infinite loop,
    but you can do it something like this:

            #!/bin/sh

            PATH=$PATH:/opt/bin
            if [ -z "$IN_KSH" ] ; then
                      IN_KSH=true exec ksh $0 $@
            else
                    (real code goes here)
            fi

    Warning - this code is not very well tested, and is not guaranteed to
    work! In particular, I don't know what the limitations of UnixWare's
    /bin/sh might be.
