After the first record of array the program gets an error.

Here's the code;

Got a couple of questins:
1. Can I use fwrit on .txt flies?
2. Teach said it's impossible to code an array of files. Still I tried coding it but no luck, so anyone here got successfully created a program that consists of an array of flies? It could be useful for creating a virus program (hehe).

Thanks in advance... :)
