Hello,

If func is a function that you have written, then the answer is easy - 
simply add a Print command to your function. For example, suppose your 
function simply added 1 to its argement:

func[x_]:=Module[{xx},
              xx=x+1;
              Print["func returns ",xx];
              xx
              ]

In practice, you may find that this gives too much output, in which case 
you could add a counter and only execute the Print every 100'th time or 
whatever.
