Hi,
My requirement is that, everyday GDG generation will be created with different data's. By the end of the month i need to collect all the GDG generation data's in a single PDS with the help of GDG base. The data's should be in the sorted order in the output file. (i.e.) the first generation data's should be in the first of my output file.
Regard's

Hi,
These two statements are bit contradictory-

Ram,
Addition to Anuj's observation -

Which one do you have in mind. PDS or PS? |

Oh..I think you are not concerned about the data 'inside' the GDGs rather you are concerned about an output such as
First GDG Data
Second GDG Data
Third GDG Data...
right? |

why don't u just use the GDG base while copying to a different file??
this wil conactenate all the generations under it... |

Hi,
Sorry let me clearly explain my requirement.
Consider that my daily job will creates a new generation every day.
for ex: From Day 1 to 30 it will create 30 generation
(i.e.) AAAAA.BBBB.CCCCC.G0001V00
AAAAA.BBBB.CCCCC.G0002V00
AAAAA.BBBB.CCCCC.G0003V00
......
AAAAA.BBBB.CCCCC.G0030V00
By the end of the month, I need to collect all the 30 generation data's into a single generation with new version
(i.e.) AAAAA.BBBB.CCCCC.G0001V01
The same thing will be repeated for next month and i need the generation data's in new version like
AAAAA.BBBB.CCCCC.G0001V02
Sorry i don't know whether it is achievable or not. Any suggestion plz let me know.. Thnx. |

I'm sure a storage specialist will have a better idea, but it seems to me to be pretty straight-forward, although you haven't mentioned if any of this needs to be more dynamic:
1. Concatenate the existing GDG's into a single dataset, in their original order:
//STEPAAAA EXEC PGM=IEBGENER
//SYSUT1 DD DSN=AAAAA.BBBB.CCCCC(-29),DISP=(OLD,DELETE,KEEP)
// DD DSN=AAAAA.BBBB.CCCCC(-28),DISP=(OLD,DELETE,KEEP)
...
// DD DSN=AAAAA.BBBB.CCCCC(0),DISP=(OLD,DELETE,KEEP)
//SYSUT2 DD DSN=NEW.SEQ,DISP=(,CATLG),...
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
2. Copy to the single new version:
//STEPBBBB EXEC PGM=IEBGENER
//SYSUT1 DD DSN=NEW.SEQ,DISP=(OLD,DELETE,KEEP)
//SYSUT2 DD DSN=AAAAA.BBBB.CCCCC.G0001V01,DISP=(,CATLG,DELETE),...
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY |

| You need to be careful about mixing generations and versions they are not the same thing. When you create the monthly use a different GDG base. |

As raak has said, use the gdg base as input dsn.
//SYSUT1 DD DSN=old.gdg.base,DISP=SHR
//SYSUT2 DD DSN=new.gdg.base(+1), blah blah blah
Unless you need the data in some specific order within the new GDG, this will work perfectly. |

Superk,
Why is it that u have mentioned all the GDG generations seperately instead of using just the GDG base??
Is there any specific idea/advantage behind doing so?? |

Only because the O/P stated that he wants the datasets processed in their original order (FIFO), not the normal order (LIFO). |
