The following GDG datasets exist: TBISUSR.TU00001.GDG.G0003V00 TBISUSR.TU00001.GDG.G0004V00 TBISUSR.TU00001.GDG.G0005V00 TBISUSR.TU00001.GDG.G0006V00 TBISUSR.TU00001.GDG.G0007V00 Which statement will always create: TBISUSR.TU00001.GDG.G0008V00 ?

  1. //DD1 DD DSN=TBISUSR.TU00001.GDG(+1),DISP=(NEW,CATLG),LRECL=80,

  2. //DD1 DD DSN=TBISUSR.TU00001.GDG(+1),DISP=SHR

  3. //DD1 DD DSN=TBISUSR.TU00001.GDG(8),DISP=(NEW,CATLG),LRECL=80,

  4. //DD1 DD DSN=TBISUSR.TU00001.GDG(8),DISP=SHR

Explanation

In a Generation Data Group (GDG), specifying DSN=TBISUSR.TU00001.GDG(+1) with DISP=(NEW,CATLG) will create a new generation that is one greater than the current highest generation. Since the current highest is G0007V00, the new one will be G0008V00. Absolute generation numbers like (8) are not standard syntax for relative GDG creation.
