Please suggest to get the output. Thank you

I need to replace mean,medain,cv with '-' if row with 'n' has less than 3.

for param='a',  s2 column has 2 for n, so I need to change the mean,median,cv to '-'.

for param='b',  s2 and s3 columns have 2 and1, so I need to change the mean,median,cv to '-'.

output needed:

3 2 4 n a
5 - 8 mean a
4 - 5 meadin a
10 - 15 cv a
3 2 1 n b
5 - - mean b
4 - - meadin b
10 - - cv b

data aa;
input s1 $ s2 $ s3 $ r3 $ param $;
datalines;
3 2 4 n a
5 6 8 mean a
4 7 5 meadin a
10 20 15 cv a
3 2 1 n b
5 6 8 mean b
4 7 5 meadin b
10 20 15 cv b

Why do you have the data is such a strange layout?

Is PARAM the key variable that let's you link the observations with N to the observations with the MEDIAN?

Why isn't the data organized like this:

data have;
  input param $ repeat n mean median cv;
cards;
a 1 3 5 4 10
a 2 2 6 7 20
a 3 4 8 5 15
b 1 3 5 4 10
b 2 2 6 7 20
b 3 1 8 5 15
;

Then the request change is easy;

data want ;
  set have;
  if N< 3 then call missing(of mean median cv);
run;
