Random access (more precisely and more generally called direct access) is the ability to access an arbitrary element of a sequence in equal time or any datum from a population of addressable elements roughly as easily and efficiently as any other, no matter how many elements may be in the set. In this procedure, we are opening our random file and one temporary file. Then copying all records except the record, which its position number kept by Position variable, into the temporary file. After that, we delete our random file and rename the temporary file by giving the same name as deleted random file.
