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...

On Linux, I get a message that where() failed: here is part of
ex.err:
/home/irv/euphoria/include/file.e:37 in function where()
where() failed on this file
fn = 3
.. called from test.exu:9
Global & Local Variables
test.exu:
fn = 3
i = 47105
So, how _do_ we know when the disk is full, in a manner that allows
the program to handle it gracefully? Rob? Anyone?
