Hi,

I have a VBS file. It has spanned records (this is shown in the output from the HISTOGRAM (an old utility from SYNCSORT), but i am not able to find exactly which records are spanned records.

Can anyone please help?

Thank You

The key question to me, is why on earth would you want to know this?

The RDW (Record Descriptor Word) at the front of each record is 4 bytes. The first two bytes are the length of the record. The second two bytes have, AFAIK, 4 possible values:
00 -- record begins and ends in the current block
01 -- record begins but does not end in the current block
02 -- record ends but does not begin in the current block
03 -- record neither begins nor ends in the current block

The 02 and 03 meanings may be swapped; it's been a long time since I looked at the manual that describes these fields.
