Bash do it : (if your shell is the Bourne Shell)
 #!/bin/bash
area[11]=23
area[13]=37
area[51]=UFOs

# Some members of the array can be left uninitialized.
# Gaps in the array are o.k.

echo ${area[11]}    #  {curly brackets} needed
echo -n "area[13] = "
echo ${area[13]}
echo "Contents of area[51] are ${area[51]}."
# Contents of uninitialized array variable print blank.
echo -n "area[43] = "
echo ${area[43]}
echo "(area[43] unassigned)"
echo
# Sum of two array variables assigned to third
