Accessing Speed Demon Accessing Speed Demon Speed Demon is a set of routines, or intrinsics, that you call from your program. The Speed Demon/V intrinsics are installed in the system SL. The Speed Demon/iX intrinsics are installed in an XL. You access Speed Demon by calling these intrinsics, just as you would the IMAGE intrinsics. There are three primary intrinsics: SPDEDBINIT. Initializes the Speed Demon environment and decides what dataset to read. SPDEDBSCAN. Replaces calls to DBGET mode-2 and returns the same condition word values (e.g., 0 for okay, 11 for end-of-file). SPDEDBSHUT. Cleans up the Speed Demon environment. Before you can call SPDEDBINIT for another dataset, you must call SPDEDBSHUT. Original Program Using DBGET Suppose that your program scans the d-sales dataset to produce a report of all d-sales records with a sales-total greater than $10,000.00. Currently, your COBOL program looks like this: Suprtool 5.7 for MPE Accessing Speed Demon • 435
