Hi,
I wonder if it's possible to join several generation datasets to one file and I want them to be copied in the order they we're created as gdg:s ?

I've tried to use utility IEBGENER but it didn't work as I wanted because the latest created gdg (G0002V00) came first in the output file (SYSUT2) and then came G0001V00.

I've got two generation file as shown below:
RXX.TEST.RXXFILE.COPY ??????
RXX.TEST.RXXFILE.COPY.G0001V00 TEST6A
RXX.TEST.RXXFILE.COPY.G0002V00 TEST6A

Then I execute this jcl:
//RXXCONC EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT1 DD DSN=RXX.TEST.RXXFILE.COPY,DISP=SHR
//SYSUT2 DD DSN=RXX.TEST.RXXCONC,
// DISP=(,CATLG),DATACLAS=TL

Sincerely,

Mikael

Not directly. You can explicitly code each dataset in the sequence you want:

or you can write a progette (probably using Rexx) to get a list of the dataset names and generate the JCL in the correct sequence.

Samples/pointers can be found in the forum as this topic has been discussed before as you would have discovered if you had done the required forum search beforehand.

If you know how many you want, you can code as (0), (-1), (-2) etc.

That's the problem.
I don't know how many gdg:s I've got when I start the job.

Regards
Mikael

Well then, follow NicC's recommendation and write a tiny piece of code to determine the number of generations and their names, and tailor the JCL with them.

If you want to reference ALL the generations in the group, just code the group-name in your JCL

Hello,

Please re(read) the topic. Doing as you suggest does not present the data in the needed order . .

Hi Monitor,

I have mutiple GDG base , and i want to concatenate them.

Some GDG base might not have versions and some might be empty,

Will the job abend if the GDG base is empty ??

if so , how to handle this condition ?

1) Please do not address posts to a specific person
2) I think Monitor has retired anyway
3) do not 'tailgate' an old topic with your new question
4) this is such a simple thing to test why do you not know the answer?
5) locked
