Your string theory took 1ms to execute, so I wouldn't stress too much about efficiency. I'm not a professional or anything, but it's worth trying.

main() {
    new
        string[144],
        i=0,
        time = GetTickCount();

    while(i != sizeof(string)) {
        switch(random(2)) {
            case 0: {
                strcat(string, "0");
            }
            case 1: {
                strcat(string, "1");
            }
        }
        i++;
    }
    print(string);
    printf("Took %dms to execute", GetTickCount()-time);
}
