Try:
SELECT INTO RS ID FROM CUSTOMER WHERE FIRSTNAME LIKE KEYWORD || ''%'' LIMIT
1;
You append KEYWORD and a '%' together using ||. You need to use
doubled quotes inside the quoted environment; one gets stripped off so
that the stored procedure will wind up containing the query:
SELECT INTO RS ID FROM CUSTOMER WHERE FIRSTNAME LIKE KEYWORD || '%' LIMIT 1;

C is almost a real language. (see assembler) Even the name sounds like
it's gone through an optimizing compiler. Get rid of all of those
stupid brackets and we'll talk. (see LISP)
