im stuck again and dont know how to write this command.
I have a data set with different clinical trials of pharmaceuticals. Each trial has a NIS Number and sometimes there was only one drug that was tested, some trials tested up to 8 different drugs.
Now I want to create a new variable, called "unique drugs". I need to know how many different drugs were tested.
Trial No. 1 Nis_Number=1234, drug = ASS
Trial No.2 Nis_Number=1235, drug= ibuprofen, drug2=Paracetamol
Trial No.3 Nis_Number=1236, drug=.
trial No. 4 Nis_Number=1237, drug=Apixaban, drug2=Eliquis, drug3=Ibuprofen, drug4=Brillique, drug5=ASS
How can I count the amount of unique drugs?
E.g. I want to know how many Trials tested ASS and how many trials was Ibuprofen tested.
Thank you so much in advance

Transpose the data set to a long format, so you have only one drug variable, and then use count(distinct()).
For code, post a data step of your dataset - see my footnotes.

Unfortunately, I have never seen or used that data2datastep macro yet. But your macro call (the RUN statement is unnecessary) would imply that you have a dataset named drugs in a library named drugs_new and you want to create an external file named uniquedrugs (presumably without a suffix such as .txt) containing SAS code for creating a copy of dataset drugs_new.drugs.
Maybe that's not what you really want.
Can you please be more specific what you mean by "it didn't work"? Error messages in the log will be helpful to understand what went wrong.
As to your initial post, you are asking two different questions:
The simplified code example below demonstrates (part of) what you can do with the "transpose" and "count(distinct ...)" techniques @KurtBremser suggested.
/* Create test data */ data have; input trial NIS_Nummer drug $ drug2 $ drug3 $; cards; 1 1234 ABC DEF ABC 2 1235 CCC DDD EEE 3 1236 DEF . . 4 1237 . . . 5 1238 CCC DEF . ; /* Transpose to a long format */ proc transpose data=have out=long(rename=(col1=drug)); by trial NIS_Nummer; var drug:; run; /* Count unique drugs per trial */ proc sql; select trial, NIS_Nummer, count(distinct drug) as unique_drugs from long group by trial, NIS_Nummer; quit; /* Count unique trials per drug */ proc sql; select drug, count(distinct trial) as trials from long where drug ne ' ' group by drug; quit;
Caveat: When it comes to counting "unique drugs", you are probably aware of the many issues which can arise if drug names in your data are not standardized (typos, upper/lower case, abbreviations, trade names vs. generic vs. substance names, ...) or missing values are denoted differently ("n/a", blank, ...).

I tried it like this but it didnt work
What did I do wrong? Can you please tell me?
%data2datastep(drugs, drugs_new, uniquedrugs);
When something "does not work", always post the log.
The macro accepts up to 4 positional parameters:
Since you specified no path for the output file, the macro probably tried to write to a location where you don't have write permission.
In case of SAS UE, I'd use a filename like /folders/myfolder/create_dataset.sas. After this is created, you can pick it up from the Windows/Linux/MacOS side with any text editor and copy/paste the contents here.
