SAS Tutorial: How to format Excel file by SAS DDE

Question: As statistician, we often got the "by-request" to automate the output, for example, automate the process to generate some beautiful excel file with specific format. How can we accomplish this?
Answer: This tutorial we will cover the following step in formatting an excel file:
        • Open and close (save) the spreadsheet
        • Setup the page orientation, centering, fitting, margins
        • Apply different column widths to the data
        • Control font size and style of titles, heading, body
        • Apply custom data fonts
        • Align data center, left, right

        options noxwait noxsync;
        x '"C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"';
        /* use office14 for office 2010, use office12 for office 2007. */
        data _null_; rc = sleep(3); run;
        /* put sas to sleep for 3 seconds to call excel */
