Re: Need basic help....

It doesn't seem to want to save my char to a file. Can anyone see what
is wrong? Ive spent a lot of time trying to figure it out and just
cant seem to work it out.

I know I have a lot of altering to do yet before I can even think im
finished. I know this doesn't answer question 4 the way it should be
done but will be altering after aswell.

Thanks again.
