vaibhav mehta :
There are similar named macro variables like temp1,temp2 etc..
temp1=xyz; temp2=abc;
Now I want to store these macro variable values into dataset.
I tried writing something as below:
%let n=2;
data current_data;
do=1 to &n.;
myvalues="&&temp&i.";
run;
But its not working. It seems that i is not getting resolved in the same dataset as it is declared in just like call symput function does.
Can anyone help?
Tom :
To dynamically retrieve the value of a macro variable at run time in a data step use symget() function, the reverse of the call symputx() function. You can use cats() to help you build the macro variable name from your integer value.
data current_data;
do=1 to &n.;
length myvalues $200;
myvalues=symget(cats('temp',i));
output;
end;
run;
You could use macro logic to generate some wallpaper code. Note that you must define a macro to use %DO loop.
%macro expand;
data current_data;
length i 8 myvalues $200;
%do i=1 %to &n;
i=&i;
myvalues="&&temp&i";
output;
%end;
run;
%mend expand;
%expand;
