Hi all,


I am having a GDG A with 110 versions with below Layout as given below in OLD-VSAMNTB and I want to copy the GDG to a new GDG B with below layout as mentioned in NEWNTB

Now I want to migrate the data in existing GDG A generation to the new GDG B of same generation number

How can I do it..

Note : The fields in red are newly added and offsets are changed?


old vsamntb

01 a.
05 B PIC X(40)
05 C OCCURS 10 TIMES
10 D PIC X(20)
05 E PIC X(40)
05 FILLER X(60)
newntb

05 B PIC X(40)
05 C OCCURS 10 TIMES
10 D PIC X(20)
10 FILLER PIC X(60)
05 E PIC X(40)
05 FILLER X(60)

Hi,

I believe you need to a short COBOL program to reformat it from Old to New.

Hope it helps

Regards

I think this is the proper SORT job:
Code:

//STEP0001 EXEC PGM=SORT                           
//SORTIN   DD   DISP=SHR,DSN=vsamntb
//SORTOUT  DD   DSN=newntb,
//         DISP=(,CATLG,DELETE),UNIT=SYSDA,       
//         SPACE=(CYL,(1,1),RLSE)                 
//SYSOUT   DD   SYSOUT=*                           
//SYSIN    DD   *                                 
  OPTION COPY                                     
  OUTREC FIELDS=(1:1,40,41:41,20,121:61,20,       
    201:81,20,281:101,20,361:121,20,               
    441:141,20,521:161,20,601:181,20,             
    681:201,20,761:221,20,841:241,40,             
    881:281,60)
