Hello,

Your data step is not working ;-).

Here's the code you are after:

data have;
LENGTH drugname $ 20;
infile cards delimiter='|';
input ID $ drugname $ ;	 
cards;
001 |sodium oral benzoate 
002 |oral sodium 
003 |oral potassium 
004 |oral Sodium 
005 |Sodium oral
;
run;

data want;
 set have;
 if upcase(scan(drugname,1,' '))='ORAL' then indicator=1;
 else indicator=0;
run;
/* end of program */
