Subject:      Re: SAS Hint - How many Observations are there in a Member ?

however the fact remains that  it is still quicker (by a long way
depending on how many sas libraries/members are defined in a session) to read
the
member header at compile using the set ... nobs method. The dictionary table
will require the whole dictionary table to be read looking for the one you
want,
while the compile time set method hones straight in to read just the header of
just
the desired member.
