In Jim's example, he's setting variables; therefore, he could test the variables with [ -z "${VAR...}" ] and create appropriate exceptions if they aren't defined.
Code:
function Parse
{
   while getopts :r:l:p:o:q:t: name
   do
     case $name in
        l) LOG="$OPTARG" ;;        # LOG FILE
        p) PROC="$OPTARG" ;;       # Process name
        o) ONE_UP="$OPTARG" ;;     # One_Up Number
        q) PRNT="$OPTARG" ;;       # q Print queue 'FTP' for now
        r) LIS="$OPTARG" ;;        # lis file name
        t) FTPDEST="$OPTARG" ;;     # D = Disk, T = Tape
        *) Usage ;;                     # display usage and exit
     esac
   done
   [ -z "${PROC}" -o -z "${PRNT}" ] && Usage
