Hi Stephen,

One more time.  I spotted a logic problem in the second set of commands
(calculating the number of years, months, days).  The following version
appears to be correct.  Someone check me on this... It's getting late in
NYC :)

DATA LIST LIST/ bdate (adate).
BEGIN DATA
02/07/75
11/01/81
12/13/76
END DATA.

NUMERIC age (f4.1).
COMPUTE age = CTIME.DAYS(DATE.MDY(9,1,2002) - bdate) / 365.25.
LIST.

NUMERIC yr (F2).
NUMERIC mo (F2).
NUMERIC da (F2).

COMPUTE yr = (2002-XDATE.YEAR(bdate)).
DO IF XDATE.MONTH(bdate) LE 9.
. COMPUTE mo = (9 - XDATE.MONTH(bdate)).
ELSE.
. COMPUTE mo = (12 - XDATE.MONTH(BDATE) + 9).
. COMPUTE yr = yr - 1.
END IF.
COMPUTE da = (XDATE.MDAY(bdate)-1).
LIST.
