Application log

Hello friends,

I have a query regarding the application log ( Transaction SLG0, SLG1 etc ). I would like to be able to write to the application log and at the same time be able to read and siplay the application log. Want to know the function modules for doing the same. It would be nice if the same could be shown with some example.

Useful answers will be rewarded.

Cheers,

Jaydeep.
