 NAME       : DOSAVE
 DESCRIPTION: LTA and PP Save Area DSECT
 DSECT      : SVEARA
 FUNCTION   : SVEARA describes the fields in a VSE Logical
              Transient Area (LTA) and Problem Program (PP)
              save area. SVEARA is called by the DOSAVE
              macro. These areas are used by DOS/VS routines
              to save the value of the PSW and registers for
              purposes such as linkage to and from transient
              routines.
