Function & Format (2)


Thanks for your answer (See included message below), 
but I'm afraid it's not exactly what I want:

I want the function fun to RETURN, say x^2, but PRINT "-FUN-".
It's like Graphics, that PRINTS "-Graphics-", but RETURNS a more
complicated object, that it's possible to re-use for any other problem:


In[1]:= g = Graphics[...]

Out[1]= -Graphics-

In[2]:= Show[%]

Out[2]= -Graphics-


It's like the difference between InputForm and OutputForm...

The function to solve your problem seems to be simple:


 fun[x_]:= ( x^2 >>> "abc";     (* This appends the result x^2 to your
                                   (existing) file  abc. 
                                   (Example for your action)
                                 *)
            "-FUN-"             (* Alternative: Print["-FUN-"]
                                 *)
           )

fun[3]
fun[4]
fun[10]


I hope, it helps
