#### SVEARA Prolog

     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.
