Q'Nial: Queen's University Nested Interactive Array Language

[top]

  1. A mixture of APL2, LISP, FP and Pascal
  2. Example: Prime number generation by two distinct algorithm(see APL, A+, J, K, yorick version). 

    primes IS OPERATION N {	
	V := count N;
	(2 match BYROWS REDUCE plus (0 match (V OUTER MOD V))) sublist V 
}

    sieve IS OPERATION N {
	R := sqrt N;
	S := o hitch take (N - 1) l;
	P := 0;
	WHILE P <= R DO
		P := P + 1 + find l (P drop S);
		S := o (rest (P * count floor (N / P)) - 1) placeall S;
	ENDWHILE;
	S sublist count N
}
