NAME       : AVRLIST
 DESCRIPTION: Volume and Device Characteristics
 DSECT      : AVRADR
 FUNCTION   : AVRADR describes the characteristics of volumes
              and devices in response to a VSE SVC 99 request
              (GETVCE). AVRADR is called by AVRADR macro
              which calls AVRLIST macro that in turn calls
              DCTENTRY macro.
