Excellent!  That is *exactly* what I was looking for!

Thanks a million, William!

I now have a command (SSCR) for saving a block of 8 screens of Forth program code onto disk with your own file name, and also another command (LSCR) for loading a block of 8 screens of Forth program code from disk by filename.  I also have a command (DIR) to take a look at the files available on disk, to check that your file got there OK, or if you need to look up the file name for loading.
