Restore following an S0 crash

Here, it is necessary to differentiate between two cases:

1. Storage levels S1 and S2 are undamaged

   The following statements are required for each damaged pubset, e.g. pubset A:

   //RESTORE-FILES FILE-NAMES=:A:$*., -
   //  MIGRATED-FILES=*CATALOG-ONLY, - 
   //  JV-NAMES=:A:$*., - 
   //  ...
   

   Normal processing can be continued on all undamaged pubsets.

   If the home pubset is damaged, it is first necessary to restore and call the procedure that defines the archive. The directory file for backups must also be restored.

2. Storage levels S1 and S2 are also damaged

   First, it is necessary to restore processing level S0. Afterwards the storage levels S1 and S2 must be restored (see the following section).
