I am currently working on a port of battlestar(from bsd-games package) to the nspire. To get comfortable with programming, I am learning how to do the basics. I have mastered basic input and output, but I am clueless as how to read a file, say "file.tns". It is all text.

Right now my code is something like this: (not exactly, but all the code pertaining to the file reading)

FILE *test;

test = fopen("file.tns", "rt");
char line[80];
while(fgets(line, 80, test) != NULL) {
   displn(line,1); //Display string with newline
}
fclose(test);
I have "file.tns" in the same directory as my program on the nspire.

The nspire displays gibberish.
Any suggestions? I am using the latest version of ndless.

So I could use:
FILE *test;

test = fopen("/documents/devel/file.tns", "rt");
char line[80];
while(fgets(line, 80, test) != NULL) {
   displn(line,1); //Display string with newline
}
fclose(test);
And it would work?

Not sure what is "rt" but yeah, should work if the devel directory exits.

You might want to go visit nTxt (which is a text editor) and look at the source.

I don't understand the source at all either
At least the solution was a pretty simple one

Well, I have only recently learned c. I admire the structure of your code, I just didn't understand the file reading part.
