My GDG has 3 generations,
test.gdg------------base
test.gdg.g0001v00
test.gdg.g0002v00
test.gdg.g0003v00

If I use below JCL then what will happen
exec pgm=iebgener
SYSUT1 DD DSN=TEST.GDG,DISP=SHR
SYSUT2 DD DSN=TEST.OUTPUT,DISP=(NEW,CATLG,CATLG)

Is that copy all 3 generations to the output dataset?

The best way to know it is to try it. No?

Remember Edison....

From the JCL reference manual, if you omit the generation number:
Quote:
A DD DSNAME parameter that requests all members of a generation data group (GDG). The system retrieves the data-set-sequence-number from the catalog.

You would probably get a few error messages for missing DD statements

Hi,

just to add to what Robert said, the latest generation is read first.

Hi,

If you are searching for the JCL, check this out.

//STEP010 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SYSPRNT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SORTIN DD DSN=TEST.GDG(0),DISP=SHR
// DD DSN=TEST.GDG(-1),DISP=SHR
// DD DSN=TEST.GDG(-2),DISP=SHR
//SORTOUT DD DSN=TEST.OUTPUT,
// DISP=(OLD,CATLG,KEEP),
// UNIT=SYSDA,
// SPACE=(CYL,(400,600),RLSE),
// DCB=(RECFM=FB)
//SYSIN DD *
SORT FIELDS=COPY

Hello,

Is there some reason you posted this jcl when the original jcl does what was required?

The original request was to copy all generations and the original jcl does this.

Also, please learn to use the "Code" tag as suggested. It will make your jcl, control statements, and data much easier to read. You can also use Preview to see how your post will appear to the forum (rather than how it looks in the Reply editor) before you Submit. After you Preview, make sure you click Submit or your post is lost (done that a few times icon_confused.gif ).
