[GRASS-user] highest and lowest point in catchment

Hello all,
I hope the questions does not seem too simple, but I have now no real good idea how to solve this simple problem:

I need to find the highest and the lowest point within catchments WITH their coordinates (and to get the information about altitude and coordinates, of course)

thanks for hints!
