The ROLLMANY() routine is an adaptation of the program presented earlier in this chapter. Since you cannot

pass parameters to a program called through a selection from a custom View menu, the exported variables

SIDES and ROLLS are used in place of the parameters that were used in the previous versions.

The program above calls two other user programs: ROLLDIE() and DICESIMVARS(). ROLLDIE() appears earlier in

this chapter. Here is DICESIMVARS. Create a program with that name and enter the following code.

The program DICESIMVARS

EXPORT ROLLS,SIDES;

EXPORT DICESIMVARS()

BEGIN

10 ▶ ROLLS;

6 ▶ SIDES;

END;
