By omitting the EXPORT command when a function is declared, its visibility can be restricted to the program within which it is defined. For example, you could define the ROLLDIE function inside the ROLLMANY program like this:

ROLLDIE();

EXPORT ROLLMANY(n,sides)

BEGIN

LOCAL k,roll;

//initialize list of frequencies MAKELIST(0,X,1,2*sides,1) ▶ L2; FOR k FROM 1 TO n DO

ROLLDIE(sides)+ROLLDIE(sides) ▶ roll; L2(roll)+1 ▶ L2(roll);

END;

END;

ROLLDIE(n)

BEGIN

RETURN 1+RANDINT(n-1); END;

In the second version of the ROLLMANY program, there is no ROLLDIE function exported from another program. Instead, ROLLDIE is visible only to ROLLMANY. The ROLLDIE function must be declared before it is called. The first line of the program above contains the declaration of the ROLLDIE function. The definition of the ROLLDIE function is located at the end of the program.

Finally, the list of results could be returned as the result of calling ROLLMANY instead of being stored directly in the global list variable, L2. This way, if the user wanted to store the results elsewhere, it could be done easily.

ROLLDIE();

EXPORT ROLLMANY(n,sides)

BEGIN

LOCAL k,roll,results;

//initialize list of frequencies MAKELIST(0,X,1,2*sides,1) ▶ results;
