Array processing, getting the variable name from an array element?

[glmsas]

In Data step processing, is there a way to get the variable name from the array element
so like this
data t;
a=1;
b=2;
c=3;
array cols{*} a--c;
do i=1 to dim(cols);

if cols(i) ='a' then .....
end;

where you want the var name not the value?
thanks
