//allo DD DISP=(NEW,CATLG),DSN=&SYSUID..REPORT.SWEU.BEFINJ(+1),
// DCB=(BLKSIZE=27920,RECFM=FB,LRECL=80),
// UNIT=SYSDA,SPACE=(TRK,(00099,00099),RLSE)
//allo01 DD DISP=(NEW,CATLG),DSN=&SYSUID..REPORT.SWEU.BEFINJ(+2),
// DCB=(BLKSIZE=27920,RECFM=FB,LRECL=80),
// UNIT=SYSDA,SPACE=(TRK,(00099,00099),RLSE)
//allo02 DD DISP=(NEW,CATLG),DSN=&SYSUID..REPORT.SWEU.BEFINJ(+3),
// DCB=(BLKSIZE=27920,RECFM=FB,LRECL=80),

Hi Vam,
Do you really want to add 5 empty datasets to the GDG? There are legitimate reasons for doing it, but is that what you were asking?
If you do, you may want to keep this in mind:
1) Don't attempt to read any of the new ds. An abend can result.
2) Depending on the LIMIT used to create the GDG you may "roll off" previously created ds by creating the new gens. And again depending on the options chosen when the GDG was created, they may be deleted.
Regards, Jack. |

if u want to add the new generations after the completion of 5 generations.U need to alter the GDG. so that u can increase the LIMIT parameter.
thanks
