B-K Dynamics activities during the first quarter (28 October 1974 to 15 January 1975) have been focused on two major areas: STINGER simulation preparation and PDDAIOS installation. This report summarizes the work performed by BKD during the above period and outlines accomplishments and plans for the next quarter. No attempt has been made to document software generated during the period since all programs described are being continually upgraded. Current listings, flow charts and program decks are stored in the ACS's 9300 room.
