Abstract

A system which utilizes a bar code having an instruction field whose data specifies an action to be performed and also having a reference field whose data relates to the data in the instruction field. The system reads the instruction and reference fields of the bar code and processess the read data. This processing may determine from the instruction field data that the action or actions to be taken are to be taken on data other than that in the reference field of the bar code. It also may determine from the data in the instruction field that an action to be taken on the data in the reference field is other than an action identified in the instruction field of the bar code. Based on these determinations, the system continues the processing using the appropriate action and data. A unique bar is also used in the system. This bar code, between its start and stop fields, has a separator field whose width is greater than that of any of the individual bar code characters.
