1) The ESDS organization will not allow you to delete the
record.
2) Using FileAid, copy first 09 record into other data set.
Which means that the new file contains only 9 records(10th
record is deleted0
3) Hope that you can use EXTEND

Answer / ajit
Deletion in ESDS can be done programatically. An indicator
bit can be set for the deleted record and those can be
escaped while reading.
Other way to replace the record with spaces.
I think OPEN EXTEND is possible in RRDS.
