Hi...I'm teaching myself SAS and am new to this community board.     I am trying to recode 12 categorical variables (pbc_1-pbc_12) with the response "yes", "no", and "unsure". In my code, "yes" = 2, "no" = 1, and "unsure" = 3.  I want to only capture the "yes" responses from the 12 variables and create one variable (precon).  I'm using "else if" statements, but the code is not working.  I also don't know if I am accounting for the "no" and "unsure" responses correctly.  I essentially want to examine the distribution of "yes" responses.    precon=.; if pbc_1 = 2 then precon = 1;  else if pbc_2= 2 then precon = 2;  else if pbc_3= 2 then precon = 3;  else if pbc_4 = 2 then precon = 4;  else if pbc_5= 2 then precon = 5;  else if pbc_6 = 2 then precon = 6;  else if pbc_7 = 2 then precon = 7;  else if pbc_8 = 2 then precon = 8;  else if pbc_9 = 2 then precon = 9;   else if pbc_10 = 2 then precon = 10;  else if pbc_11 = 2 then precon = 11; else if pbc_12= 2 then precon = 12; else precon = .;   Please help any way you can.  Also, if there is a more sophisticated way of doing this type of procedure please let me know. Thanks! Trace ... View more
