Sas what is the significance of january 1st 1960
We'll take a look at several of the informats that are available in SAS later in this lesson. For now, we'll just refresh our memory of how to write the formatted style input statement that is necessary to read in dates. First, note that the mmddyy8. Incidentally, the 8 in mmddyy8. You could alternatively use hypens - or blank spaces between the mm and dd and yy. Also note that the period is a very important part of the informat name. Without it, SAS may attempt to interpret the informat as a variable name instead.
Then, launch and run the SAS program, and review the resulting output to familiarize yourself with the contents of the diet data set. Well, geez, I guess the other thing that the output illustrates is that it is not enough just to tell SAS what informat to use to read in a date's value, but you also have to tell SAS what format to use to display a date's value.
If you don't, as you see here, the dates that are displayed are not particularly user-friendly! As the preceding example illustrates, we have to tell SAS in what form we would like our dates displayed. The form that a date takes in output is known as a date format. Do we want the date displayed in the form Dec 1, ? Again, there seem to be as many SAS date formats as there are ways that you could imagine writing a date. The best thing about SAS dates is that, because SAS date values are numeric values, you can easily sort them, subtract them, and add them.
