Using SAS

Create a bonus variable of $$1,000\mathrm{.}00$ for employees who are leads, managers, or directors, and $$0$ otherwise.

Here is what I did:

Data bonus;

Set employees;

If index$($Title$,$ 'Lead', 'Manager','Director'$)$ Then Bonus$=1000$;

Else Bonus$=0$;

run;

When I run this everything comes up $0$ under bonus because the titles are listed as "Engineering manager" or "Lead java engineer" I$\text{'}$m not sure how to sort to find just the lead manager director words
