The r-subt.p procedure determines the amount of inventory available by subtracting the amount allocated from the total on hand.

FOR EACH Item NO-LOCK: 
  free-stock = Item.OnHand - Item.Allocated. 
  DISPLAY Item.ItemNum Item.ItemName Item.OnHand Item.Allocated free-stock. 
END.

Note

Subtracting one decimal expression from another produces a DECIMAL value. Subtracting one INTEGER expression from another produces an INTEGER. Subtracting an integer expression (INTEGER or INT64) from a decimal expression (or subtracting a decimal expression from an integer expression) produces a DECIMAL value. Subtracting a mix of INTEGER and INT64 expressions produces an INT64 value.
