ASCII Sort Order ChartWhen you select information for sorting, it is important to understand how characters are evaluated by the system. The ASCII (American Standard Code for Information Interchange) guidelines are followed. This means internationally accepted standards for character values are used when determining sort order. So, when you create a sort for a report, you should know, for example, that the customer name Baker prints before the customer name baker, since B precedes b in ASCII sort order. The following chart lists characters in ascending order. Reverse the order to print in descending order.
