The phmenu menu script that you created and tested in Hands-on Project 6-15 still needssome work, because it doesn’t contain a way to call applications after they are selected. In this project, you solve this problem by adding case logic to the menu.

To make additions to the phone menu script:

1. If you have interrupted your development process and have just logged back in or switched to another directory, change to the source directory and use the pwd command to verify you are in that directory.

2. Use the vi or Emacs editor to open the phmenu file in your source directory. In the following lines, add the lines that are boldfaced to the script:

#========================================================

3. Save the file and exit the editor.

4. Test the script. (Acceptable entries are A, a, P, p, S, s,V, v, Q, and q. Any other entries cause the message “Invalid Code” to appear.) Type Ctrl+c to exit when you are finished testing.
