Assume that you will create the specifications for an automated project tracking system for the Training employees. One of the system's functions will be to allow project members to update or add names, addresses, email addresses and phone numbers of new clients. Using structured English, write a procedure for carrying out the process of entering a new client name, address, email address and phone numbers.

(Hint: The procedure should ask for a client name, check to see if the name is already in an existing client file, and let the user either validate and update the current client address, email address, and phone number [if necessary] or add a new client's address, email address, and phone number to the client file.)
