Hai All,

While we write a record in RRDS, The relative record number is automatically generated, like first records as 1 and second record 2 and so on. But I want to start the RRN from 100 means how? Please help me...


With Regards

Probably the same way you would start a browse with a keyed file......

You want to start writing a new dataset and have the first record in that dataset be RRN #100?
Or start re-writing an existing dataset at RRN #100?

You can't, not with a RRN file...you do realize that RRN satand for Relative Record Number, don't you? And that is relative to the beginning of the file, so the first record would always be #1 and the hundredth would always be #100........

Thanks for your kind information... But i'm thinking that we can make the relative record number for starting record in the RRDS as user wish? And rest of the records are sequential 101,102,103.... so on..

Why would you want to start from 100 ?

And if you think about the problem the solution is relatively easy.

But there again why not consider the use of an INDEXED file, such as a KSDS.

No.

WRITE for relative files
For OUTPUT files, the WRITE statement causes the following actions:
v If ACCESS IS SEQUENTIAL is specified: The first record released has relative record number 1, the second record released has relative record number 2, the third number 3, and so on.

Hello,

You need to use the technology as it is implemented - it will not change to meet some "user wish".

If your user wants to see things begin with 100 - fine, but you will have to provide that. A relative record number will not.
