SPSS® 12.0 Command Syntax Reference

64 Universals
on the first day of the first month of the quarter, a DATE9 print format
for the same value is displayed as 01-OCT-57.
DATE.MOYR(m,y) Combine month and year. The value of the month must be expressed
as an integer between and including 1 and 12. The year can be
expressed as two or four digits. For example, the command
COMPUTE START=DATE.MOYR(MONTH,YEAR).
displays NOV 57 for START when MONTH is 11 and YEAR is 57 and
the print format is MOYR.
DATE.WKYR(w,y) Combine week and year. The week must be an integer between and
including 1 and 53. The year can be represented by two or four digits.
For example, the command
COMPUTE WEEK=DATE.WKYR(WK,YEAR).
displays 26-NOV-57 for WEEK when WK is 48 and YEAR is 57 and the
print format is DATE9. The number of the week in the WKYR format is
calculated beginning with the first day of the year. It may be different
from the number of the calendar week.
TIME.HMS(h,m,s) Combine hour, minute, and second into a time interval. For example,
the command
COMPUTE PERIOD1= TIME.HMS (HR,MIN,SEC).
produces an interval of 45,030 seconds for PERIOD1 when HR equals
12, MIN equals 30, and SEC equals 30. The value can be displayed as
12:30:30 with a TIME8 print format.
You can supply one, two, or three arguments. Trailing arguments can be
omitted and default to 0. The value of the first nonzero argument can
spill over into the next higher argument. For example, the command
COMPUTE PERIOD2=TIME.HMS(HR,MIN).
produces an interval of 5400 seconds for PERIOD2 when HR is 0 and MIN
is 90. The value can be displayed as 01:30 with a TIME5 print format.
You can have a non-integer value for the last argument. For example,
the command
COMPUTE PERIOD3=TIME.HMS(HR).
produces an interval of 5400 seconds for PERIOD3 when HR equals 1.5
and is displayed as 01:30 with a TIME5 format. When you supply a
nonzero argument to a function, each of the lower-level units must be
within the range of −60 to +60.
TIME.DAYS(d) Aggregate days into a time interval. The argument can be expressed
as any numeric value. For example, the command
COMPUTE NDAYS=TIME.DAYS(SPELL).
with a value of 2.5 for SPELL generates a value for NDAYS that is displayed
as 2 12:00 with a DTIME7 format.
