From a glance at your code it seems that you don't understand control
flow. When a procedure or function is called, control is passed with
the intention that control is passed back when the procedure or
function completes. 

So.... what you need if I understand your intention, is a loop in your
main procedure which is terminated by selecting quit, and your other
procedures to just 'return' (i.e. don't attempt to call main, just
complete).

Hope that helps
