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. Note that these are just a few examples of SAS Informats, and there are many more available for use depending on the type and format of data being read into SAS. SAS Formats are used to change the appearance of data in a SAS data set, without actually modifying the underlying data values. Formats are used to control how data values are displayed in output, such as reports or graphs, and can also be used to sort or group data. Formats can be applied to either character or numeric data types. Character formats are used to display character data in a specific format. Numeric formats are used to display numeric data in a specific format. Informats are used to read data into SAS, while formats are used to display data in a particular way.

Informats are used to read data into SAS, while formats are used to display data in a particular way.

An informat is a specification for how raw data should be read. A format is a layout specification for how a variable should be printed or displayed. To see a list of all internal formats and informats, type 'help format ' in the command line and then click on 'SAS Formats and Informats ' in the resulting window. The code above only creates the format, it does not associate it with any variable. Formats can be associated with variables in either data steps or proc steps.

Note that this use of a one-level name differs from the use of a one-level name elsewhere in SAS. The name of the catalog entry is the name of the format or informat. The entry types are as follows:. Informats and formats are temporary when they are stored in a catalog in the WORK library. You can retrieve temporary informats and formats only in the same SAS session or job in which they are created.

SAS format is the instruction that specifies how the value of a variable should be printed or displayed, and SAS informats are the specification for how raw data should be read. Formats and informats for a variable may or may not be the same for the variable. For a complete list of built-in formats, you can refer to SAS 9. SAS informats are declared when you are reading in data or creating a new variable in a data step, whereas the format statement can be used in either a data step or a proc step:.
