Fantastic!! I'm so glad I came to this site!

I figured out a way to assign the variables, cleaned up my code a bit also and it all works. Just one more question if possible, and my internet research into the select command has so far turned up nothing. Instead of having to pick the number from the menu list, is it possible to use the name of the variable instead?

So instead of:

1) Tom
2) Dick
3) Harry
4) Quit

What would you like to choose: 3

As well as, or instead of, 3, you could write "Harry" and it would work. Obviously, the case function would throw an error if it wasn't 3 or Harry, for example you wrote Harryyy.

One more thing. I have created 3 files, FileA File B and File C. I want to set it so only FileA can be opened if Tom was selected previously, File B if Dick was selected previously, nd FileC if Harry was selected previously, else error. I figured the code might be something like:

Code:

case ${_name} 
    in  quit) break ;;
    in  Tom) cat FileA ;;
    in  Dick) cat FileB ;;
    in  Harry) cat FileC ;;
       '') print -u2 "You must select one of the above [${names}]" ;;
       *)  _myName="${_name}"; break ;;
    esac
    REPLY=''
  done

Cheers for all your help! I have never done programming before, but you have helped learn loads.
