assign variable values to array variable

[dht115]

In following example, I want to assigned test1 value to try1, test2 value to try2, test3 value to try3.

DATA have;                     
   input IDnumber $ test1 test2 test3;    
   datalines;           
aa 1 0 0 
bb 0 0 0 
cc 0 0 1
dd 1 1 1
;                             
RUN; 

DATA want;
set have;
array try {3};
RUN;

I tried following, but did not work.  

Data want;
                Set have;
                Array try(3) test1-test3;
Run;

Desire output should be:

DATA want;
set have;
array try {3};
array t test1-test3;
do over t;
 try(_i_)=t;
end;
RUN;

 Basically, you have grouped the existing vars into an array. And what you need is another assignment array to copy the values using indexed loop sequential look up. HTH
