A lookup is a program that is used to display transactional or other data in a list format. A lookup is normally written using an object called a browse. A browse is a program that presents information in a list format. A browse normally allows you to sort and search the information that is displayed in the list using several different display sequences, and it also allows you to customize the information that is displayed in the list for each display sequence. Some look up programs in StreamV also use SQL queries to display data.
