When using a line pointer control to read in raw data, which statement is FALSE?

When using a line pointer control to read in raw data, which statement is FALSE?

• A. you can use / to move up or down one line
• B. #n can be used to go to any line that you desire
• C. You must have the same number of records for each observation that is being created
• D. All of these are false

Answer: (A)

When using line pointer control in SAS to read raw data, it's important to understand how the mechanisms work. The correct assertion in this context is that you can indeed use the line pointer control feature, specifically the forward slash (/) to start reading data from the next line, and that the notation #n allows precise movement to specific lines within the input. The statement claiming the necessity for having the same number of records for each observation you are creating is misleading. Line pointer control allows handling irregular data, meaning you can read varying numbers of records for different observations, as long as the logic in your reading statements accommodates such variability. This flexibility is a defining feature of using line pointer control. Thus, since statement A inaccurately asserts that the forward slash only allows movement up or down one line (when it actually allows only moving down to the next line), it stands out as the incorrect statement among the provided choices. This understanding is critical for anyone working with SAS to effectively read and manipulate raw data through line pointer control.
