Lists and TUI's

Here is a program I used with year 9 to introduce list basic list functions and TUI's.
It contains:

• selection
• procedures
• procedure calls
• casting 
• pop
• remove 
• lists 
• append

It is a very simple simulation of a "game server" allows the user to add gamer tags, remove and pop off the end of the list. 

Here is the code : link
