I am learning Fricas with the hope I can write Fricas script for CAS 
integration tests directly.

I am having hard time figuring how to check the type of variable. I looked 
at Fricas book but it shows no examples.

(11) -> n:Integer   
                                                                   Type: 
Void
(12) -> n:=10
   (12)  10
                                                                Type: 
Integer
(13) -> typeOf(n)
   (13)  Integer

Now I want to check, using if then else, that "n" has type "Integer". How 
to this? For example, this gives error

     if typeOf(n)=Integer then output("type is integer")

I tried few other permutations of the above, but they all give errors.

Thanks
