The Digital Lookup Engine is a user configurable search / list lookup and selection utility program. It was originally created for use in my MAS90/MAS200 enhancements as a universal substitute to use instead of modifying their ChUI "List Mode" programs. Originally released as a ChUI utility, in 2000 I added GUI capabilities, so that in the MAS90 environment, it will present a Graphical interface when running in a GUI program, and a ChUI interface otherwise, using the same program driven from the same list definition. The DLE has distinct advantages over the MAS ALE in the GUI envrionment, as it is page driven, similar to a load-on-demand object. The user does not need to wait for a large file to be loaded into a windows object. Overall response time is significantly faster. An additional display field area shows selected record data for the currently highlighted list entry. This enables the user to view significantly more information when the DLE is used to generate inquiry displays. A list definition maintenance program is used to setup, define and customize each list definition. One simple CALL statement invokes the list: CALL "DXZLPA", TERM$, LISTNAME$, VALUE$, STATUS Runtime options may be passed to the DLE in order to effect a number of list definition parameters under program control. Contact Me for more information if you are interested in using this utility in your MAS90/MAS200 development or for any other ProvideX project. |
