Informats by Category

There are five categories of informats in SAS:

Category Description

CHARACTER instructs SAS to read character data values into character variables.

COLUMN-BINARY instructs SAS to read data stored in column-binary or multipunched form into character and numeric values.

DATE and TIME instructs SAS to read data values into variables that represent dates, times, and datetimes.

NUMERIC instructs SAS to read numeric data values into numeric variables.

USER-DEFINED instructs SAS to read data values by using an informat that is created with an INVALUE statement in PROC FORMAT.

For information on reading column-binary data, see Reading Column-Binary Data. For information on creating user-defined informats, see the FORMAT procedure in the SAS Procedures Guide.
