Progress - 4GL, show the qty of difference for same item from two different excel in to single excel.

/* program take input from two excel sheets and show the same item with same rate and their   corresponding value in same row ,*/
/* if not found same item with same rate , then fetch the first record for the item from second sheet and show this record with not matched record */
/* item found in one sheet but not in another sheet will show with the zero value for the sheet for which it is not found */
