Hi,
I have a dataset with var1 var2 ...var100.
I want to code the below macro idea:
%macro test(x=);
Data have;
if var_&x = 3 OR var_&(X-1)=3 OR var_&(x-4)=3 then find=1;
run;
%mend;
so if X=10, the code will check var10, var9 and var6 value.
Yes, I can make it %macro test( x=, y=, z=) .
But I wonder if we can do anything similar this idea.
Thank you,
HHC

%macro test(x=);
Data have;
var_10=3;var_9=3;var_6=3;
if var_&x = 3 OR var_%eval(&X-1)=3 OR var_%eval(&x-4)=3 then find=1;
run;
%mend;
%test(x=10)

Use an array.
%let x=10;
data have;
array var(100) var1-var100;
if var(&x)=3 or var(&x-1)=3 or var(&x-4)=3 then find=1;
run;
