The GROCERY.PRG program illustrates how to use the VALID clause to skip over GET objects. The GetItem() function returns a number to the VALID clause which skips to the proper "units" (items, weight, volume) depending on the grocery item (Bread, Apples, or Milk) selected. Then, when the approprate quantity is entered, the VALID clause skips over the other "unit" fields to the name field. For example, the VALID 2 clause skips over two fields (or get objects).
