[dba-SQLServer] Returning a dataset

A stored procedure can return a data set correct?  Is that data set
updateable?

I need to run a stored procedure, where I pass in the Value for the TOP N
(the N part) and then build up a SQL statement and execute that inside of
the sp.  That sp needs to return the data set to another SP, and that SP has
to update a field in the data set returned by the first sp.

Is this possible?  

ATM I have a view called TopN, which returns a date field.  I have a query
that updates that date field to today's date.  The problem is that the TopN
view is hard coded with a number (30000 for today's order) but that value
could be any number.  So I need to turn the view into a SP where I can pass
in the number of records to update and then pass the set up date fields back
to an update SP to do the update.
