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 */
