1、Chapter 5: Enhancing Your Output with ODS “Some men see things as they are and say, Why. I dream things that never were and say, Why not.“ Robert F. Kennedy From Respectfully Quoted: A Dictionary of Quotations from the Library of Congress, edited by Suzy Platt, copyright 1992 by Library of Congress.
2、 Based on George Bernard Shaw, Back to Methuselah, act 1, 1949. 5.1 Concepts of the Output Delivery System You might think that procedures produce output. They dont. Technically, procedures produce only data. Then they send that data to the Output Delivery System (ODS) which determines where the out
3、put should go and what it should look like when it gets there. That means the question to ask yourself is not whether you want to use ODSyou always use ODS. The question is whether to accept default output or choose something else. ODS is like a busy airport. Passengers arrive by car and bus. Once a
4、t the airport, passengers check baggage, pass security, eventually board a plane, and fly out to their destinations. In ODS, data are like passengers arriving from various procedures. ODS processes each set of data and sends it off to its proper destination. In fact, different types of ODS output ar
5、e called destinations. What your data look like when they get to their destination is determined by templates. A template is a set of instructions telling ODS how to format your data. These two conceptsdestinations and templates are fundamental to understanding what you can do with ODS. Destinations
6、 Starting with SAS 9.3 if you dont specify a destination, your output will be sent, by default, to HTML when you use the SAS windowing environment in Microsoft Windows or UNIX. With SAS 9.2 and earlier, the default destination was LISTING. LISTING is still the default for programs run in batch or in
7、 other operating environments. Here are the major destinations: Most of these destinations are designed to create output for viewing on a screen or for printing. The LISTING destination is what appears in the Output window in the SAS windowing environment, or in the listing or output file if you use
8、 batch mode. The MARKUP destination is a general purpose tool for creating output in formats defined by tagsets. This includes XML (eXtensible Markup Language), EXCELXP, LaTeX, CSV (comma-separated values), and many other formats where data can be thought of as separated by tags. The OUTPUT destinat
9、ion creates SAS data sets. The DOCUMENT destination, on the other hand, allows you to create a reusable output “document“ that you can re-render for any destination. So, if your boss decides he really wants that report in PDF, not RTF, you can replay the output document without having to rerun the e
10、ntire SAS program that created the data. With an output document, you can also rearrange, duplicate, or delete tables to further customize your output.

12、 common types of templates are table templates and style templates (also called table definitions and style definitions). A table template specifies the basic structure of your output (which variable will be in the first column?); while a style template specifies how the output will look (will the h
13、eaders be blue or red?). ODS combines the data produced by a procedure with a table template and together they are called an output object. The output object is then combined with a style template and sent to a destination to create your final output. 1 You can create your own table and style templa
14、tes using the TEMPLATE procedure. However, PROC TEMPLATEs syntax is rather arcane. Fortunately, there are other, easier, ways to control and modify output. The quickest and easiest way to change the look of your output is to use one of the many built-in style templates. To view a list of the style t
15、emplates available on your system, submit the following PROC TEMPLATE statements: PROC TEMPLATE; LIST STYLES; RUN; A few of the built-in style templates are ANALYSIS D3D MINIMAL SASWEB BARRETTSBLUE HTMLBLUE PRINTER SANSPRINTER BRICK JOURNAL RTF STATISTICAL Notice that RTF and PRINTER are names of bo
16、th destinations and styles. Some styles work better with certain destinations than with others. HTMLBLUE is the default style for HTML output, RTF is the default style for RTF output, and PRINTER is the default style for output sent to the PRINTER, PDF, and PS destinations. A few procedures, most notably PRINT, REPORT, and TABULATE, dont have ready-made table templates. Instead, the syntax for these proce
