What does the #n option control in SAS?

The #n option in SAS is used to specify a line number to jump to when reading data from a raw data file. This feature is particularly useful for skipping to a specific point in the data file that may contain the relevant information you wish to process, allowing for efficient data handling in situations where not all lines of the input file are necessary for the analysis.

The other options do not accurately describe the functionality of the #n option. The first choice pertains to reading records, which is handled by different SAS functionality such as the INFILE statement and INPUT statement. The character length for inputs is controlled through informats, and the number of iterations to perform is generally managed by loop controls within SAS programming, not through this particular option. Understanding the exact purpose of the #n option helps clarify how to effectively navigate and manipulate data files in SAS programming.
