Dear All,
I have a large dataset with diagnosis codes that are up to four digits. I need to make them more uniform by adding zeros preceding the first digit (letter) to make them 4 digits but in a character format.
I've tried this but I end up with all zeros.
data diagnosis;
input diagnosis;
datalines;
094
16
E4
;
run;
data diagnosis;
set diagnosis;
diagnose=translate(right(diagnosis),'0',' ');
;
run;
My desired output would be this:
0094 |
0016 |
00E4 |
First of all, your first data step won't really work, as you try to create a numeric variable, so add a dollar sign:
data diagnosis;
input diagnosis $;
datalines;
094
16
E4
;
run;
Then try this:
data diagnosis;
set diagnosis;
length newdiag $4;
newdiag = '0000';
substr(newdiag,5-length(diagnosis)) = diagnosis;
drop diagnosis;
rename newdiag=diagnosis;
run;

Perfect. This works well.
data want; var="E4"; want=cats(repeat('0',3-lengthn(var)),var); run;
data diagnosis;
input diagnosis $;
datalines;

run;
data diagnosis;
set diagnosis;
length newdiag $4;
newdiag = diagnosis;
newdiag= translate(right(newdiag),'0',' ');
run;
