通过示例学SAS(9)--显示数据

1.显示前n个数据。OBS=n,如

title "First Five Observations from SALES";
proc print data=learn.sales(obs=5);
run;

2.在report 过程中产生新变量

title "Computing a New Variable";
proc report data=learn.medical nowd;
   column Patno Weight WtKg;
   define Patno / display "Patient Number" width=7;
   define Weight / display noprint width=6;
   define WtKg / computed "Weight in Kg"
   width=6 format=6.1;
   compute WtKg;
      WtKg = Weight / 2.2;
    endcomp;
run;
