is exactly what I needed.
Mags
here is one solution:
NEW FILE.
DATA LIST LIST / id (f8.0) st_date d_date end_date (3adate10).
BEGIN DATA
1 , 05/03/2007 , 09/22/2007 , 01/06/2008
2 , 02/03/2009 , 09/22/2011 , 01/06/2010
3 , , 04/29/2009 , 08/11/2011
END DATA.
LIST.
COMPUTE good_decision = d_date GE st_date and d_date LT end_date.
FREQUENCIES good_decision.
