    Write(savefile/F)
        ..()
        F["last_dir"]<<src.dir
        F["last_x"]<<src.x
        F["last_y"]<<src.y

                switch(alert(src,"Are you sure you wish to delete your save file?","Delete Save File?","Yes","No"))
                    if("Yes")

            else
                src<<"<b>No data found.</b>"


WHAM-O! That's a simple saving proc done in about 30 seconds. Of course, you can take these same basic concepts and elaborate on it and create something much more.

Here's a comprehensive write-up:

And here's a library that will do it for you, or from which you can learn code concepts:
