Sample 48287: Use the CHARTYPE option in PROC MEANS to get binary representation of the _TYPE_ variable
 |  |  |  |  |  |
You can specify the CHARTYPE option in the PROC MEANS statement to get a character representation of the binary value of the _TYPE_ variable in the output data set. Click the Full Code tab to see an example.
The macro in the sample code shows how you can post-process the PROC MEANS output data set to create a data set variable containing the list of class variables that contribute to each observation.

x=int(ranuni(j)*13) +1;
y=int(ranuni(x)*13) +1;
z=int(ranuni(y)*13) +1;
output;
end;
end;
