Thanks for handling my questions.

I understood the "-inst" purpose, and it works perfectly well in the following
sample :

/usr/OV/bin/mibtable -table . -fields
Name=3:25,Size=5:11,Used=6:11 -inst 1,2 -node <nodename>

where I get the first two instances of the hrStorageTable. But my concern was 
the sentence "Also, an asterisk (*) can be used as a pattern-matching character 
the  end of an instance." extracted from the man pages...
