Sales slip processing method, sales slip processor using sales slip processing method, and storage medium used for sales slip processing method and processor

摘要

In response to inputting order, a sales slip processor issues a sales slip with a slip code and a table code of a table at which the order is accepted, and stores order data in a sales holding file. In order to balance or rewrite sales slips, an operator inputs a sales slip code or a table code. The processor calls order data sets with a table code corresponding to the input code from the sales holding file and numbers the sets to create and store an edit data group in an edit file. One edit data set is selected and displayed on a screen display part. A data set next to the displayed edit data set can be retrieved from the edit file through one touch operation that designates a subsequent or previous slip with an input unit and displayed on the screen to thereby facilitate the retrieval of the order data with the same table code.
