https://communities.sas.com/t5/SAS-Procedures/IN/m-p/71357#M20599 Hi Luis,<BR /> <BR /> You got it right. It takes the value of 1 if X is equal to 1 or 3.<BR /> <BR /> Regards,<BR /> Milton Tue, 15 Sep 2009 02:10:09 GMT milts 2009-09-15T02:10:09Z https://communities.sas.com/t5/SAS-Procedures/IN/m-p/71354#M20596 Hi all,<BR /> I am new in SAS and I am trying to interpret some codes. <BR /> I found the following line:<BR /> DBPLANT=X IN (1 3)<BR /> I haven't found the explanation for the IN command. Does it means that variable DBPLANT takes value of 1 if X is equal to 1 or 3, or if X is belongs to the closed interval 1 through 3. <BR /> Thanks in advance,<BR /> Luis Tue, 15 Sep 2009 00:51:53 GMT https://communities.sas.com/t5/SAS-Procedures/IN/m-p/71354#M20596 luis 2009-09-15T00:51:53Z https://communities.sas.com/t5/SAS-Procedures/IN/m-p/71355#M20597 Yes, the operand(s) in parantheses can be separated by a blank or comma.
