You can use the SAS DATA step to write the Haver converted series to a SAS data set so that you can easily analyze the data using the SAS System. You can specify the name of the output data set in the DATA statement. This causes the engine supervisor to create a SAS data set with the specified name in either the SAS Work library, or if specified, the Sasuser library.
When OUTSELECT=OFF (the default), the contents of the SAS data set include the date of each observation, the name of each series read from the Haver database, and the label or Haver description of each series. Missing values are represented as '.' in the SAS data set. You can use the PRINT procedure and the CONTENTS procedure to print your output data set and its contents. You can use the SQL procedure along with the SASEHAVR engine to create a view of your SAS data set.
The DATE variable in the SAS data set contains the date of the observation. The SASEHAVR engine automatically maps the Haver intervals to the appropriate corresponding SAS intervals.
When OUTSELECT=ON, the OUT= data set does not contain the observations of all time series. Instead, each observation contains the name of the time series, the source of the time series, the geography1 code, the geography2 code, the short source, and the long source for that time series. In addition, the contents of the OUT= data set shows every selected time series name and label. See Output 41.11.1 and Output 41.11.2 for more details about the OUTSELECT=ON option.
