Using latest snapshot,
      
      Calling min() and max() with no dataset in place returns the
      error:
      
      <error>
      ? eval min(m)
      No dataset is in place
      Terminated on error
    </error>
    
      
      Simply execute the following:
      
      <hansl>
      matrix m = seq(1,4)
      
      # both fail
      eval min(m)
      eval max(m)
      
      # works
      eval maxc(m)
      eval maxr(m)
      </>
      
      This must be due to a recent change, as I just ran a script which
      worked before.
      
      Best
