Our tutorials reference a dataset called "sample" in many examples. If you'd like to download the sample dataset to work through the examples, choose one of the files below:. In SAS, formats and informats are pre-defined patterns for interpreting or displaying data values. In this tutorial, we'll focus on SAS's built-in formats, which mostly cover numeric, date, and character variables. Suppose I tell you that a person's birthday is on How do you know if I mean "December 1, " or "January 12, "? That's quite a difference!

It creates a dataset called sampledata which is stored in WORK library. In this case, 8 and 10 refers to width of the date. The created dataset looks like below -. It returns as it is in SAS date value form. It is not meaningful if you look at the value. You cannot tell which date it is. Result : It returns as 30DEC is the today's date. The 10 refers to the width of the date as contains 10 elements. The PUT statement is used to show value in log window. No need to specify width in this format. It automatically adjusts the width depending on the month. The DAY. Deepanshu founded ListenData with a simple objective - Make analytics easy to understand and follow.

SAS Informats and Formats play a vital role in data analysis because they help to ensure that data is read and displayed accurately. They also help to simplify data analysis tasks by allowing users to specify the way data is formatted and processed in SAS. SAS Informats and Formats are used to validate the integrity and accuracy of data. Informats instruct SAS on how to read data values by specifying the data type, length, and format of the input data. Character informats are used to read character data into SAS data sets. Numeric informats are used to read numeric data into SAS data sets.

You must specify at least one variable when specifying an informat or when including no other arguments. Numeric informats are applied to numeric variables, and character informats are applied to character variables. These default informats apply only to the current DATA step. SAS reads the variables by using the scanning feature of list input, but applies the informat. In modified list input, SAS. The SAS windowing environment allows you to associate, change, or disassociate informats and variables in existing SAS data sets. This example associates a character informat and a numeric informat with SAS variables. Although the character variables do not fully occupy 15 column positions, the INPUT statement reads the data records correctly by using modified list input:.

It is also just good practice to look at the variable informats so that you understand the dataset better. SAS Enterprise Guide. Flickr Flickr. Please check the below sample code. Numeric informats are used to read numeric data into SAS data sets. In SAS, formats and informats are pre-defined patterns for interpreting or displaying data values. Dates and date-times are the most important case of this. If you do not include an informat code after a variable name, SAS will assume the "default" informat: a numeric variable of "size" 8.
