     I want to re-ask a question I asked before about designating a 
     variable as an integer.  On page 261 of the 3rd edition of
Mathematica 
     it talks about making an integer assignment, i.e. "f[n_Integer] is 
     like defining a function f that must take an argument of "type" 
     Integer.   I try this in a function like f[x_,n_Integer]:=Sin[n Pi 
     (x/a)] and then type f[a,n] and expect the answer zero but it just 
     gives me Sin[n Pi].  What have I misunderstood here?
