To the external user there is no such thing as a directory block within a PDS-E 
- the member information is just taken from the general space within the 
dataset.

That will depend on a couple of things.

A rule of thumb I have used is 

Loadlib 4 members per DIR Blk
Source 7 member per Dir Blk if ISPF Statistics are OFF Source 4 member per Dir 
Blk if ISPF Statistics are ON

I do not have numbers for PDS/E datasets and Directory Blocks.

I have not looked at this in a while.  But this usually works for me.
