Hi all,
How can I create a new variable that is the count of other variables?
For example,
DATA TESTTEMP;
INFILE DATALINES TRUNCOVER;
INPUT ID DX1 DX2 DX3 DX4 DX5;
CARDS;
1 8 32 21 24 45
2 8 23 3 , ,
3 23 44 56 3
;
RUN;
PROC PRINT DATA=TESTTEMP;
RUN;
What I am expecting is the output dataset like this
ID DX1 DX2 DX3 DX4 DX5 NDX
1 8 32 21 24 45 5
2 8 23 3 3
3 23 44 56 3 4
Best,
Liang
ndx=n(of dx:);
ndx=n(of dx:);
