Jess doesn't have an explicit else-if feature; if you put an "if" into
the "else" of another "if", then that second "if" is a separate
function call, so it needs its own parentheses.
If I may, I will point out a few other things here: You don't need to
spell out the names of any classes in java.lang, as it's implicitly
imported, just as in Java. Second, you don't actually need to
construct Strings at all; you can call Java String methods on Jess
strings. Third, you can (and should) always omit "call" when calling a
Java instance method; it's really only needed when you're invoking a
static method. So you could clean your function up like this:
(deffunction compare-comptment-function(?s1 ?s2)
(if (eq ?s1 ?s2) then
(return "FFF")
else (if (?s1 contains ?s2) then
(printout t "COMES 1" crlf)
(return ?s1)
else (if (?s2 contains ?s1) then
(printout t "COMES 2" crlf)
(return ?s2)
else
(printout t "COMES 3" crlf)
(return (str-cat ?s1 , ?s2))))))
