Examples

Example 1: Specifying Numeric Informats

The PROC FORMAT step in this example creates a format, READDATE., that formats the variable values 1 and 2 with the name of a SAS date informat. The DATA step creates a SAS data set from raw data originally from two different sources (indicated by the value of the variable SOURCE). Each source specified dates differently. After reading a record, the DATA step uses the value of SOURCE to create a variable, DATEINF, that contains the value of the appropriate informat for reading the date. The DATA step also creates a new variable, NEWDATE, whose value is a SAS date. The INPUTN function assigns the value of NEWDATE based on the source of the observation and the appropriate informat.
