Line 111. Is that the start of a function or what?

[rubberman]

@ddanbe - I think it is a continuation of main, but he exits main in his while(choice) loop back on line 79. And there is no final return value at the end (line 140).

[ddanbe]

@rubberman: you're right I guess, those dreadful, wrong posted indentations!

Main ends at line 80. I think what is needed is a function header just before line 112.
