I want to write a bash function to display keys and values of an associative 
array.
Have done as follows.  Is it simply a matter of using $1 and $2 for tho 
associative
array name and title?

keyv ()
{
  echo "$title"
  for key in "${!aa[@]}"; do
    echo "Key:   ${key}"
    echo "Value: ${aa[$key]}"
  done
}
