File Size and Retention

[Sanchez, Kenny J]

 
Hello!!
 
How can I do the following:
 
I would like to create a log file and would like to SET THE FILE SIZE and
RETENTION period.
 
I would like to set the file size to 500KB and only save a weeks worth of
that file.  
 
Can someone point me in the right direction/send me an example???
 
Thanks,
 
Kenny
