Data extraction from edat file

[David McFarlane]

Again for the record, I just want to add a plug 
for using the Analyze facility built into 
E-DataAid.  This does a nice job of handling a 
variety of basic descriptive statistics for 
initial looks at the data, and with proper use 
does a marvelous job of organizing data for 
export to other analysis programs.  Please study 
the E-DataAid sections of the Getting Started 
Guide, User's Guide, and Reference Guide that 
come with E-Prime.  As I have said before, it is 
almost worth getting E-Prime just for for its 
data handling capabilities, which are sadly much overlooked.
