 NAME       : LWRD
 DESCRIPTION: LINEWRT Data Descriptor
 DSECT      : LWRD
 FUNCTION   : LWRD is used to map an area of storage that
              contains information on data output that is used
              by the LINEWRT Macro with FORM=MULTIPLE.  This
              descriptor DSECT has two formats.  It describes
              either the positioning of the cursor within a
              VSCREEN or the output that is to be written to a
              VSCREEN.
