Hello @knveraraju91 ,

chemOTHERapy and immunOTHERapy also contain the string 'OTHER' of course.

Maybe this code helps you out?

data one;
input a $40.;
datalines;
contains OTHER
contains CHEMOTHERAPY
contains IMMUNOTHERAPY
contains IMMUNO
;
run;

DATA TWO;
SET ONE;
where scan(upcase(a),2)='OTHER'; 
*IF index(UPCASE(A),'OTHER');
RUN;

Good luck,

Koen

INDEXW or FINDW to find words. Index and Find will find strings embedded in longer words.

DATA TWO;
SET ONE;
IF indexw(UPCASE(A),'OTHER');
RUN;

Indexw has an optional parameter for providing delimiters between words in case the blank is not sufficient. Suppose you have text like: this*that=something.

If you want to find "that" as a word you could provide * and = as additional delimiters:

   if indexw(str,'that',' *=') then ...

Note the inclusion of the blank so that other places blank is still used as a delimiter.

Findw is similar but has a few more parameters and can use modifiers to indicate things like "all punctuation" and Ignore case for comparisons.
