Okay /comp/. I've been considering making a program on Fortran lately, and today I finally moved my ass and tried to make first attempt. I failed though. I couldn't even start the program. The program I'm trying to make should create a phonebook(names, surnames and phone numbers). I asked my teacher's help and all he said was:

Ask the number of entries.
Read user input to an array.
Write this array into a file in the harddisk
My program should avoid multiple entries. If a record already exists my program should ask whether the user wants to update the entry.

It also should be able to search the created database and find a phone number by name, if required.


What I'd like to get from you if not the whole program, which is sort of impossible, at least a clue on how I make it.
