I know the following code works well, but does anyone have alternative suggestions to write a more efficient code that replaces zeros with missing values?
Here is a sample dataset:
data work.sample;
infile cards expandtabs truncover;
input ID shrout shrout1 shrout2;
cards;
26232409 0 2 50997000
26232409 0 3 50997000
26232409 53598 0 50997000
10623630 10097 2 0
5856168 . . .
;
run;
Here is the code:
data work.sample;
modify work.sample;
array vars{*} shrout shrout1 shrout2;
do i = 1 to dim(vars);
if vars{i}=0 then call missing(vars{i});
end;
run;

Perfect, thanks for pointing that out, @Reeza.
