Hi,

I want to sort a variable length record. So, when I need to specify the starting position of the elements based on which the records to be sorted, should I give the starting position as we see in the file OR should I add 4 to the starting position as we see in the file?

Thanks,
Cheers.

Hi,

Yeah u should be adding 4 bytes to the starting byte for the VB file.

Thanks,
Madhavi

For VB records, the first data byte starts in position 5 after the 4-byte RDW. When you view the records, the RDW is often hidden, but it's still there as far as DFSORT is concerned. You need to include the RDW when specifying the starting position, so you'd add 4 to the starting position of the data byte. For example, for the second data byte, you'd specify a starting position of 6 (4 for RDW + 2).
