Write a program that finds entries in the database created in Exercise 1 based on

information provided by the user of the program. The statement

can be used to connect unit 19 to file “pfile” created by the program in the previous exercise. “old” indicates that the file is already there; “rewind” says to position

the file at its beginning; and “read” indicates that the file will only be read and

nothing will be written to it.
