hi,
I have not yet taken the coupon for the exam.
but still i would like to know...
When the database is a flat file.
how do get a lock on a record. as there is nothing unique there.
or is it that my way of thinking itself is wrong

You're thinking about it incorrectly. It doesn't matter whether the data is in a flat file or in a table. You can still think of the data organized in to records. Each record does have unique information to identify a specific record.
