Value of a function at one point

If f has been defined earlier then it is possible to write a:=f(1.2,3.1); Then a has the value of f at x=1.2 and y=3.1 .

It is also allowed to do

x1:=1.2; 
y1:=1.6; 
a:=f(x1,2*y1); 
save('a.dta',a);
Remark: Recall that ,a being a scalar, its value is appended to the file a.dta.
