array problem

Hi community,

I'm not sure if my output is correct for this array problem. Any suggestions are greatly appreciated. Thank you!

1. Set up arrays to meet the following requirements:

Array math has three elements, Jan, Feb and Mar. Their initial values are “January”, “February” and “March”.
Since the array statement will be the first reference to these variables, pay particular attention to their length.;

Below is my answer:

data b;
array math (3) Jan Feb Mar;
do i=1 to 3;
end;
proc print;
run;


Obs	Jan	Feb	Mar	i
1	.	.	.	4

I think this is not a situation where arrays are needed! But ... it seems as if the answer is expected to contain usage of arrays. And thus a very poor question.

Nevertheless

array math {3} $ 8 jan feb mar ('January','February','March');

This will do

data b;
   array math{3} $ Jan Feb Mar ('January' 'February' 'March');
run;
