For elseifnotequal, the conditional block is executed if all
previous conditional blocks were false and A is not equal to
B (i.e. A != B).
A
A may be a number or a variable.
B
B may be a number or a variable.
Example:
;@ iflessthan(X, 10) ; If X is less than 10 then show "doll0.cel".
;@ map("doll0.cel")
;@ elseifnotequal(X, 15) ; Otherwise, if X does not equal 15 then show "doll2.cel".
;@ map("doll2.cel")
;@ endif()
