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

A Correct answer
Explanation

GDG (Generation Data Group) relative references always create the next generation. Option A uses GDG(+1) with DISP=NEW, which correctly creates the next generation (G0008V00) regardless of existing generations. Options C and D use absolute references (GDG(8)), which requires that generation to already exist. Option B incorrectly uses DISP=SHR when creating a new dataset.
