Oh yes I forgot that I can use a floppy.

I tested this program

object fn,i
fn = open("A:\\filefull","wb")
include file.e
include get.e
i=0
while 1 do
    puts(fn, "x")
    i+=1
    printf(1, "%10d   %10d\n", {i, where(fn)})
    if get_key() != -1 then exit end if
end while



Here is the result (confusing):
(my floppy disk is about 136 KB free)

In DOS:
puts() runs normal and no error messages, but the file pointer
(where()) is increasing, then decreasing, then increasing... and so
on. You can try the example above. Very strange. And puts() DOES NOT
write to disk when it's full..

How I know that puts() really write to disk?
And how I know if the disk is full...
