     NAME       : LDRST
     DESCRIPTION: Loader Storage Area
     DSECT      : LDRST
     FUNCTION   : Mapping macro that maps the CMS LOAD
                  and INCLUDE command work area. LDRST describes
                  the fields of the work area used by the loader.
                  The work area is obtained and built dynamically
                  by DMSLDR from CMS free storage. LDRST is
                  called by the LDRST macro.
