Yes, this works great in the console!
However I can see why it is better to stick to the standard functions. In my
case, this does not work when running via an Ant apply task, since Ant has its
own loggers and is doing something internally which prevents jumping to the
start of the line. Perhaps there is a way to do this with Ant, but I do not
think this is a good idea for portability...
Thanks for the insight, Daniel

Sorry, now I got it. You could try something like this:
for $i in 1 to 100
let $string := string-join((
(: yields 
, and jumps to the beginning of the current line :)
string:cr(),
'FORTSCHRITT: ',
(1 to $i idiv 5) ! '.',
$i, '%'
))
return (
prof:sleep(50),
(: calls System.err.println($string) :)
Q{java.lang.System}err() => Q{java.io.PrintStream}print($string)
)
I think we won’t offer a built-in function for that, as the result of functions
like fn:trace, prof:dump, etc. will be sent to different output channels, some
of which won’t allow the overwriting of output that has previously been sent.
Hope this helps,
Christian
