data test;
infile sample;
input a 1-2 b $ 3-6;
if a=12;
c=a*2;
run;
What happens to the obsrvation with a^=12? Is it deleted altogether? Why is it not output to test with c =null value?How subsetting if statement functions as to conditional if then/else statement?
Yes it is deleted. if statements with no then statements are effectively:
if a=12 then continue, else delete statements.
If you want to operate conditionally then use:
if a=12 then do;
c=a*2;
end;
OR in this case because you only have one statement:
if a=12 then c=a*2;
