A QUESTION:HOW TO DEFINE A FUNCTION

shiyiming

for example:
*ab is a function defined by ourselves;

ab(in1,in2)
{return in1+in2;}

c=ab(1,2);
so c will be 3;
thanks.

data d1;
input a1 a2;
a3=ab(a1 a2);
datalines;
1 2
3 4
;
proc print data=d1;
run;
d1 will be:

1 2 3
3 4 7

My question is how to define the function ab()?

Really thanks.

一般用宏来定义“函数”。
如果一定要你这样的形式，要写SCL的。
