Code:
VAR = 0;
RETAIN VAR;
is the easiest way. If you explain -- in detail -- what you're looking for, we can provide a better solution. But based on what you wrote, this code will give you a variable initialized to zero and kept for all observations.

Since you didn't tell us anything about what you want to reformat, just how do you think we can provide any assistance?

Maybe you want something like this in your proc sql?

select ...
<one or more columns>,
0 as var-name
from <table>
