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.

gzexe

GZEXE(1)						      General Commands Manual							  GZEXE(1)

NAME

       gzexe - compress executable files in place

SYNOPSIS

       gzexe [ name ...  ]

DESCRIPTION

       The  gzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``gzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
