Macro variable with array

[dera]

Hello,

I would like to know how to define macro variables using the array function.

Here is what my code looks like :

data _null_; set have;

array var {*} var_1-var_5;
do i = 1 to dim(var);
call symput ("var_(i)", (var_(i)));
end;

run;

Do you have any suggestions on how I can improve it so that it works?

Thanks

Can you tell us what you are trying to do?  I can see you probably want to create 5 macro variables but if HAVE has more that one obs you will still only have the values from the last obs of have.  Maybe you don't need these macro variables at all.  When you start putting a lot of data into macro variables "things" get messy.

There are a lot of obs in the HAVE data set so there is a do-loop command right before that.

Maybe something like this but it is messy.

data have;
   do id = 1 to 5;
      array var_[5];
      do i = 1 to dim(var_);
         var_[i] = ranuni(1);
         end;
      output;
      end;
   run;
data _null_; 
   set have;
   array var_[*] var_1-var_5;
   do i = 1 to dim(var_);
      call symputx(cats('ID_',id,'_',vname(var_[i])),var_[i],'G');
      end;
   run;
%put _global_;
