Yes, just catalog a new dataset:

Code:

//STEPXXXX EXEC PGM=ICEGENER
//SYSUT1   DD   DSN=XK.LM.S010F01.G0147V00,DISP=SHR
//SYSUT2   DD   DSN=XK.LM.S010F01.G0147V01,
//         DISP=(,CATLG,DELETE),UNIT=....
//SYSPRINT DD   SYSOUT=*
//SYSIN    DD   DUMMY


after which the existing GDS entry XK.LM.S010F01.G0147V00 will be rolled off and uncataloged and replaced with the new entry XK.LM.S010F01.G0147V01.

Hello,

It is a version (rather than a generation).

It (version) is nearly never used for files created by a business application. . . .

Unless there is some pressing business reason to use this, suggest you be aware of version and then never use it. . . icon_smile.gif

If generation A.B.C.G0001V00 is cataloged and you now create and catalog A.B.C.G0001V01, the new entry is cataloged in the location previously occupied by A.B.C.G0001V00. The old entry is removed from the catalog, to make room for the newer version, and may or may not be scratched depending on what limit processing options are specified for the GDG base.

For SMS DSNs, if scratch is specified, the older version is scratched from the volume. If noscratch is specified, or if the attempt to scratch the DSCB fails, the older version is not scratched and the generation data sets is recataloged as a non-VSAM data set with the GnnnnVnn name not associated with the GDG base.

For non-SMS DSNs, if noscratch is specified for the base, the older GDS version is not scratched.

Try allocating a new "version" for an existing GDG & look the entris in 3.4, you might get hands-on experience...icon_biggrin.gif
