Although I don't see the purpose of the above code snippet there is a
difference between existing and non-existing file:
If dat exists (and can be opened without error) then the rewrite is not
done. So in this case dat is only opened for reading and existing data is
not deleted (yet).

I would also suggest changing that to

yuansu= packed record
This will ensure that the size of the data (SizeOf(yuansu)) will be

In that case you could simply do with a rewrite(dat). The reset(dat)
is really not n
