Example 3 (DATE command)

DATE DAY 1 5 HOUR 3 8. 

• This command creates four variables (DATE_, CYCLE_, DAY_, and HOUR_) in a file where observations occur hourly.
• For HOUR_, the starting value is 3 and the periodicity is 8.
• For DAY_, the starting value is 1 and the periodicity is 5. Since DAY_ is the highest-order variable and it has a periodicity assigned, variable CYCLE_ is automatically created.

DATE reports the following:

  Name        Label

  CYCLE_      CYCLE, not periodic
  DAY_        DAY, period 5
  HOUR_       HOUR, period 8
  DATE_       DATE.  FORMAT:  "CCCC D H"

The following is a partial listing of the new variables:
