New variables in array with lower bound other than 1

I am trying to use an array to create a new variable while preserving the old variable. The variables end in a number that range from 27-55, so I want my array range to match that. When I define the range with the existing variables, I get what I expect:

array test (27:55) x27 . . . x55; *These arrays refer to the correct variables;

But when I try to create a new variable:

array testb(27:55);

do i=27 to 55;

if test(i) = 1 then testb(i) = 5;

if test(i) = 2 then testb(i) = 10;

end;

I get the following variables

testb1 . . . testb29

Is there a way to define testb27-testb55 as new variables in an array? Thanks in advance for the help!

Is there a reason you can't name them that way?

array testb(27:55) testb27-testb55;

Here is one way:

data want (rename=(testb1-testb29=testb27-testb55));

array testb(27:55);

do i=27 to 55;

if i le 40 then testb(i) = 5;

else testb(i) = 10;

end;

output;
