2.3.6. Range Operator |
If M and N are of type INT, then the expression: M .. N returns * the list [M, M+1, ... ,N] if M <= N; * the empty list, [], otherwise. If x and y are indeterminates in a ring, then x .. y gives the indeterminates between x and y in the order they appear in the definition of the ring. |
Example |
1..10; [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] ------------------------------- Use R ::= Q[x,y,z,a,b,c,d]; z..c; [z, a, b, c] ------------------------------- |
