    Well, I wouldn't just put it down entirely to a bug. Sometimes various compilers and systems protect you from yourself. If you compiled what I posted, and it still doesn't work, let me know. Make sure we're compiling the same program and using the same file.

    Edit: Make sure there's a newline at the end of the file you use. Otherwise, you'll use an EOF char.

    Thanks again for the help, so far. When I compile and run this:
    Code:
    #include <stdio.h>
    
    #include <stdlib.h>
    
    #include <string.h>
    
    typedef struct wildroom{
    
            int x;
    
            int y;
    
            char symbol;
    
    } wr;
    
    int main(){
    
            FILE *minimap;
    
            wr wilddata[6][6];
    
            int x,y;
    
           
    
            minimap = fopen("./minimap.txt","r");
    
           
    
            if(minimap==NULL)
    
            {
    
                    printf("Error in File Read\n");
    
                    exit(0);
    
            }
    
           
    
            for(x=0;x<6;x++){
    
                    for(y=0;y<6;y++){
    
                            wilddata[x][y].x=x;
    
                            wilddata[x][y].y=y;
    
                            wilddata[x][y].symbol = fgetc(minimap);
    
                    }
    
            }
    
           
    
            for(x=0;x<6;x++){
    
                    for(y=0;y<6;y++){
    
                            printf("%c",wilddata[x][y].symbol);
    
                    }
    
                    /*printf("\n");
    
                    */
    
            }
    
                           
    
            fclose(minimap);
    
           
    
            return(1);
    
    }
    On a text file that looks like this:

    Code:
    01234
    56789
    abcde
    fghij
    klmno
    It spits out this:

    Code:
    01234
    56789
    abcde
    fghij
    klmno
    
    That happens in CYGWIN after compiling with gcc. However, when I use the online compiler here:

    http://www.groovyweb.uklinux.net/?pa...ry=onlinetools,

    I get a dos file that runs perfectly and outputs the file perfectly. Any ideas on what could be causing the extra 'garbage'character?

    Shouldn't this line:
    Code:
     for(x=0;x<6;x++){
    read:
    Code:
     for(x=0;x<5;x++){
    If your text file is:
    01234
    56789
    abcde
    fghij
    klmno
    That's only 5 lines, numbered 0-4.

    The recommended change ends me up with:

    Code:
    01234
    56789
    abcde
    fghi
    And that's it. I lose one character on the fourth line, and the entire fifth line. Again, when I compiled it 'as-is' it runs fine under dos. If you look a bit higher in the thread, it runs fine on another's linux system.

    Is anyone else using CYGWIN, or familiar with this type of problem?

    Don't blame cygwin. Many people use it, and I seriously doubt it has anything to do with this.

    When you're new, you should pick a decent compiler and then be absolutely against the notion of your compiler being the source of any problems. Put the blame on yourself, because you'll probably be the source of the trouble 99&#37; of the time.

    Did you make sure that your file has an extra '\n' in it like I stated?
