What happens when the following SAS program runs? ODS HTML FILE='results'; PROC PRINT DATA=work.ds1; RUN; ODS HTML CLOSE;

When the SAS program runs, an HTML file is created with a default extension of '.html', which aligns with the behavior of the Output Delivery System (ODS) in SAS. When you use the statement ODS HTML FILE='results';, SAS interprets this as a command to create an HTML file with the specified name. If no file extension is provided, SAS automatically appends '.html' to the name given. Therefore, instead of simply having a file named 'results', the generated file will actually be named 'results.html'.

This mechanism ensures that the output is correctly saved as an HTML document, which can be viewed in any web browser, giving users the necessary accessibility and functionality associated with HTML files. The program then proceeds to execute the PROC PRINT procedure, which outputs the contents of the dataset specified (in this case, work.ds1) into this HTML file. Finally, the line ODS HTML CLOSE; finalizes and closes the output destination.

The options mentioning that nothing happens or that there is a syntax error do not accurately capture the functionality of ODS in this context, as SAS is designed to handle this scenario gracefully, automatically adjusting the filename to ensure compliance with expected output formats.
