Date and Time Manipulation with INTNX

The program uses a `_NULL_` DATA step to generate and display variables without creating a permanent dataset. It initializes three variables (`date`, `datetime`, `time`) and applies specific formats to them (`date7.`, `datetime16.`, `time8.`). The `INTNX` function is used to shift dates and times: by month for `date`, by datetime day for `datetime`, and by hour for `time`. The resulting values are then written to the SAS^© log using the `PUT` statement.

Data is created directly within the DATA step from date and time literals.

DATA STEP Data

Explanation :
This `_NULL_` DATA block initializes date and time variables. It applies formats for display and uses the `INTNX` function to calculate new values based on time intervals (month, day, hour). Finally, it displays the results in the SAS log.
