What is the default behavior when using the FLOWOVER option in an INPUT statement?

When the FLOWOVER option is used in an INPUT statement, it allows the program to continue reading the next line of data if a record is incomplete or has missing values for certain variables. This behavior is particularly useful in situations where data records may not always align perfectly with the variables defined in the INPUT statement. With FLOWOVER, if the input statement encounters a missing value, it does not stop processing the current record; instead, it seamlessly flows over to the next record to fill in the missing information, thereby maintaining data continuity.

This is important for data processing and analysis because handling incomplete data can often be a challenge. By utilizing the FLOWOVER option, SAS minimizes the likelihood of skipping records unexpectedly, thus enhancing data loading efficiency and integrity. In contrast, the other responses indicate behaviors that would either restrict data processing or stop functionality, which do not align with the purpose of the FLOWOVER option.
