I have a field UNITNUM with values for treatment.  I write in an EpiData 
Analysis program:

define u #### global
set echo=on
freq unitnum /vl
set echo=off
u=?Enter unit to analyze?
select if unitnum=@u

to prompt interactively which of the many units I wish to select for 
subsequent analysis. Any suggestion, how to modify the program to be 
able to either make the selection for a specific unit (as now) or 
alternatively not to make a selection to analyze the full set?

Thanks for any suggestion,
