menu

Hello,

I would like to know what is the best solution to create simple menu with functionality described below (pseudo code) just like im used to:

while (true){ x = readLine(); case (x): x == "1" then do sth1 function x == "2" then do sth2 function }

thanks for help, maybe any other ideas on how to make menu not in pattern described above?
