title "This is title 1" ;
data one;
  do i=1 to 10;
    output;
  end;
run;
proc print; run;
title2 "This is title 2";
title3 "This is title 3";
data two;
  do j=1 to 5;
   output;
  end;
run;
proc print; run;

proc sql noprint;
  select TEXT into : MYTITLES separated by ", "
  from SASHELP.VTITLE
  where NUMBER in (1,2,3);
quit;

%put &mytitles;

这里学习的是
1.SASHELP.VTITLE存储是数据集中的TITLE的文本对象
2.SQL中与宏的结合使用，将在SASHELP.VTITLE查询结果赋值给宏变量 MYTITLES 。
