What is the difference between (+0) and (-0) when i refer a GDG generation in my JCL?

superk

None. Zero (0) = minus Zero (-0) = plus Zero (+0).

Hi,

In JCL, current version with 0 ( Ex. MYPDS.SYS.TEST(0) )
new version to create with +1 ( Ex. MYPDS.SYS.TEST(+1) )
older versions , refer with -1 -2 -3 etc....
( Ex. MYPDS.SYS.TEST(-1) )

Thanks,
KS

SuperK was right!!

There is no difference in (+0) and (-0) GDG Generations.
If you try to use (+0) or (-0), it only refers to current version of GDG.

hi,
there is no difference. 0 represents current greneration. GDGBASE (-) represents previous generation and GDGBASE (+) represents next generation.

-0 as well as +0 are same & there no diffrence between them. Instead of these different versions of GDG are present -1,0,+0 - sign indicates previose version of dataset & + sign denotes newer one.
