Informat specifies the type of data (numeric or character), the width of the input data, and how the data is to be interpreted. It is used to convert raw data into a SAS data set. In SAS, format and informat are two methods used for data input and output.Īn informat is a SAS instruction that tells SAS how to read data. By specifying the delimiter used to separate the variables, SAS can read and process the data quickly and accurately, without the need for pre-formatting the data. The name input method is useful when working with data that is not in a fixed format, such as data from surveys or questionnaires. The first variable “var1” is a character variable that is delimited by a comma and read until the next comma or end of line, and the second and third variables “var2” and “var3” are numeric variables that are delimited by commas and read until the next comma or end of line. When the data is read using this input method, SAS reads the data from left to right and assigns the values to the appropriate variables based on their names. The INPUT statement defines the variables to be created, and each variable is separated by the delimiter in the input record. This SAS software tutorial describes the data step and several of its most common options.In this example, the INFILE statement specifies the external file to be read, and the DLM= option specifies the delimiter used to separate the variables in the input record (in this case, a comma). It also has help with common errors, under the SAS link.
