The purpose of any index is to provide the most efficient
access to the records in a file. Say you have a file of
employee names and numbers. Usually the primary index will
be the employee number. If you request a record by
providing the empl#, the access will be very fast. If you
have to very often request a record by the empl name, you
may want to create a second (a/k/a alternate) index based
on the name. So when you provide a name, the access to the
correct record also will be very fast.

There are 5 fields and 1000 records in a file. Unload it into an array. Write the syntax for declaration and how will you unload it.
