![]() To enter date values after the DATALINES statement you need to do two things: So, how do you enter date variables when you create a SAS dataset manually? ![]() So, if you have two columns (for example, salary and bonus) and you want to apply the DOLLAR12.2 format to both of them, then you need the following FORMAT statement: FORMAT salary bonus DOLLAR12.2 How to Enter Date Variablesīesides character and numeric variables, SAS provides date variables.Ī SAS date variable is stored as the number of days between January 1 st, 1960, and the given date. ![]() The names of the variables to which you want to apply the format.To apply a format to several variables, your FORMAT statement needs the following structure: Like the LENGTH statement, you can use the FORMAT statement to apply the same format to multiple variables at once. If you want to know more about user-defined formats and how to create them, I highly recommend you to read this article. With the FORMAT statement, you can apply predefined SAS formats and user-defined formats. If you want to apply a format to your input variables, you need to place the FORMAT statement after the INPUT statement. So, for example, if you want to apply the DOLLAR12.2 format to the salary variable you need the following statement: FORMAT salary DOLLAR12.2 The format you want to apply and a semicolon.The name of the variable to which you want to apply the format.The FORMAT statement consists of 3 parts, namely: You can modify the default formats with the FORMAT statement. format for numeric variables and the $ w. LENGTH FirstName LastName $25 How to Change the Format of Input VariablesĪnother frequently asked question about creating a dataset manually is how to format the input variables.īy default, SAS uses the BEST w. To change the length of both columns to 25 characters, you use the following code. Suppose you have a dataset with two columns, namely FirstName and LastName. However, you can use the LENGTH statement also to change the length of multiple variables at once. As the example below shows, this is too short for an employee with the name Hernandez (9 characters).Ībove we demonstrated how to change the length of one variable. However, for character variables, this corresponds to just 8 characters. For numeric variables, this is enough to store numbers of 16 digits. The length of a SAS variable is by default 8. If you create a SAS dataset manually, then all input variables have a default length. How to Change the Length of the Input Variables The Cards statement is an alias of the Datalines statement. Note: Instead of using the Datalines statement, you can use the Cards statement. After the last row of input, there is one final line of code with one semicolon.Īs you can see, when you enter character data it isn’t necessary to write the values between quotes. Each row of input data is written on a separate line (without a semicolon at the end). The data you want to enter follows directly after the DATALINES statement. If you don’t provide anything, SAS assumes this input variable is numeric. A dollar-sign after a variable name indicates that this variable is a character variable. With the INPUT statement, we define the names and the types of the input variables. The dataset above consists of one character variable ( employee) and one numeric variable ( salary). If you don’t specify the library, then the dataset will be saved by default in the WORK library. We use the DATA statement to define the name of the dataset ( employees) and the library where it’s stored ( work). The DATALINES (or CARDS) Statement to specify the data in your dataset.įor example, we can use the following SAS code to create a dataset with employees’ names and their salaries.The INPUT Statement to define the names and the types of the variables in your dataset.The DATA Statement to begin a DATA Step and to specify the name of your dataset.The last one is known as instream data and is a convenient way to quickly create a dataset with a small amount of data.Ī SAS program to enter data manually consists of at least 3 statements, namely: In SAS, you can create a new dataset by reading data from an input file (Excel, CSV, TXT, etc.), by using an existing dataset, or by entering the data manually.
