Hi,

I would like to know how to automatically determine the number of items in & type(=26) instead of declaring 26 in the below script....
Just a very simple example:

 

%let type= A B C D E F G H I J K L M N O P R S T U V W X Y Z ;

data _NULL_;

do i = 1 to 26;   <---- this value of 25 is what I would like to automate when I change &type.

put Number=i ;

end;

run;

Assuming they're always space separated then the countw function should do the trick like so

 

%let type= A B C D E F G H I J K L M N O P R S T U V W X Y Z;
data _NULL_;
do i = 1 to countw("&type");  
put Number=i ;
end;
run;
