Hi,

I need to copy a GDG tape file to another tape file with the DCB parameters of input GDG tape file.

As we cant refer back the DCB parameter of GDG files.

Can anyone suggest me.

Thanks,
Revathi.

Hi Revathi,

You can use below sort job, if you comment the DCB parameter of sortout file it will copy the DCB parameter of sortin file.

Code:
//XXXXXXXX JOB (XXXX),'SORT JOB',CLASS=X,MSGCLASS=X,             
//         NOTIFY=&SYSUID,REGION=4096K                           
//STEP00   EXEC PGM=SORT                                         
//*                                                             
//SYSOUT   DD SYSOUT=*                                           
//SYSPRINT DD SYSOUT=*                                           
//SORTMSG  DD SYSOUT=*                                           
//*                                                             
//SORTIN   DD DSN=INPUT,DISP=SHR                                 
//SORTOUT  DD DSN=OUTPUT,                                       
//            UNIT=(TAPE,,DEFER),                               
//*           DCB=(&GDGMODL,RECFM=FBA,LRECL=133,BLKSIZE=16625,   
//*           TRTCH=NOCOMP),                                     
//            LABEL=EXPDT=99000,                                 
//            VOL=(,RETAIN,,6),                                 
//            DISP=(NEW,CATLG,DELETE)                           
//*                                                             
//SYSIN    DD *                                                 
      SORT FIELDS=COPY                                           
//*                       


Regards,

Hello,

And you believe this because. . .?

As Expat requested - what happened when you tried this?

On a similar note - if you use sort or iebgener to copy a file (gdg or not) the output will be given the dcb attributes of the input unless you specify otherwise.

Might there be some interference due to the rather outdated practice of having a model dscb defined for the output file?
