In both cases, you can either type out the MAP command (as in the examples 
above) or select the command from the CAT menu.

The following call to function MAP uses a program instead of a function as 
second argument:

In Chapter 3 we introduced the use of the DEFINE function ( „à)  to 
create functions of real numbers with one or more arguments.  A function 
defined with DEF can also be used with list arguments, except that, any function 
incorporating an addition must use the ADD operator rather than the plus sign 
(+).  For example, if we define the function F(X,Y) = (X-5)*(Y-2), shown here 
in ALG mode:

we can use lists (e.g., variables L1 and L2, defined earlier in this Chapter) to 
evaluate the function, resulting in:

Since the function statement includes no additions, the application of the 
function to list arguments is straightforward.  However, if we define the function 
G(X,Y) = (X+3)*Y, an attempt to evaluate this function with list arguments (L1, 
L2) will fail:

     

To fix this problem we can edit the contents of variable 

@@@G@@@ , which we can list 

in the stack by using …
