Answer / janardhan
we can delete by usinf the files concept.
if case of sequential file there is no direct delete option.
for this
1) read the record and rewrite with spaces.
2) read record from one file and write it into another file
by excluding the record which has to be deleted.
if case of indexed file we can directly delete the record
as it contains the indexed no.
same for relative files.

Syntax for deleting record.
DELETE file_name RECORD
