Umm, Keith, none of this is actually compilable C code.  :-)  I think you
should be looking at something like the following:

#include 
#include 

struct names {
    char firstname[30];
    char lastname[30];
    char address[80];
} writenames;

int main(void)
{
    FILE *fp;

    strcpy(writenames.firstname, "Andrew");
    strcpy(writenames.lastname, "Clarke");
    strcpy(writenames.address, "Melbourne, Australia");
    fp = fopen("record.dat", "wb");
    if(fp) {
        fwrite(&writenames, sizeof(writenames), 1, fp);
        fclose(fp);
    }
    return 0;
}

Somehow I doubt that.  ;-)

fp = fopen("myfile", "wb");

I think you'll find that as far as XTree is concerned, only files with
certain extensions (eg. .EXE, .COM, .OVL, .BIN) are treated as binary
files.  Other programs may well treat those same files differently.
