I ran into this piece of code and I wonder if the DO loop approach is purposeful:
Approach:
data want;
set have;
if var_a = 'Tom' then do; /*Do loop needed?*/
if var_a = 'Johnny' then var_b = 'Johnny Walker';
else if var_a = 'Don' then var_b = 'Don Julio';
end;
run;
Equivalent(?):
data want;
set have;
if var_a = 'Johnny' then var_b = 'Johnny Walker';
else if var_a = 'Don' then var_b = 'Don Julio';
run;
I just need some confirmation if the DO loop is necessary at all here...
I can't see it doing anything....especially since the only time it would be evaluated is when var_a='Tom"....which of course means that neither of the two other expressions would be true.
