[Mediawiki-l] $wgOut during extension execution

[Gunter]

Hello,

I am writing a special page extension that does a mass creation of 
articles. Since there will be a lot of articles created, the extension 
takes some time to finish, especially when putting in some sleep-time.

The user should have some kind of progress information, which could be a 
single text line.

My problem is, that the page is only displayed once before the user hits 
the start button and once after the code has finished.

Is there a way to place some output on the screen without exiting the 
extension code?

Thank you for help,
