<p>A system and method of obtaining information from a price look-up (PLU) file (44) which employ an application programming interface (API) (33) which isolates application programs (35) from each other. The system preferably includes a first computer (24), a second computer (40) coupled to a storage medium (36) containing the PLU file (44), control software executed by either or both computers (24,40), an API having hooks into the control software, and a program (38) executed by the first computer which attaches into the API via interprocess communications for obtaining information for an item from the PLU file. <IMAGE></p> |
