Using eval means you can pass names as string parameters, put that string into a command string, and eval theat command string to get the shell to re-parse it as script. For instance:
Code:
pick_an_arg(){
  arg_no=$1
  shift
  eval 'echo "$'"$arg_no"'"'
 }

lets you print the fourth arg using arguments: 3 ? ? fourth_arg ? ? ? ?
