fscanf and EOF in TurboC

[Michael J. Schmelzer]

Hello everybody! I have a real problem. (?!?)
I am using Turbo C to read through a "master file" which contains
the names of all of the files to be read into my program.
I'm using fscanf(fp, "%s", filename);
Here's the problem: I don't know how to test for EOF in this
situation. For some reason, it seems that fscanf WON'T put the
file pointer at EOF when the last name is read; it will just keep
returning the last name in the file. ( feof() doesn't work!) 
I've built a workaround:
the last line in the master file MUST be
    END
I use the conditional
    while (strcmp(filename, "END")) {
	...
	}
It works, but it's just not a very robust way of doing things.
Any ideas how I can my program more robust for the end user?
Is this a quirky implementation of fscanf?
Thanks a lot!!
