If you have important new fields to display, then it is a problem to find space for them. Probably needs another screen. The -v screen is already very dense but only partly well-organized. I would move the swap stats off it first, since I haven't used swap for almost 20 years. I also find the top lines with memory statistics almost useless. The least useful vm fields seem to be ozfod, %ozfod, intrn and cache, and the most useless field is still 'buf'. Bruce
