Thanks Barry for quick reply. After I type ./ex5 -help | grep view, it comes out a list of options related to _view, all of which have the tag <FALSE>, what does this mean?

  Run as./ex5 -help | grep view to see the possibilities.  It depends on PETSc version number. When using the graphics want you generally want a -draw_pause -1 to stop that program at the graphic otherwise it pops up and disappears immediately.

I'm testing from my MAC the same commands listed on that page, for example, ex5 -dm_view, nothing interesting happen except the Number of Newton iterations is outputted. I'm expecting that the PETSc numbering would show up as a graphic window or something. Can anyone tell me what's missing here? Thank you!   ( Hui )
