A sequence is represented by a sequence of elements separated by
commas, without delimiters or with either parentheses (( and
)) or seq[ and ] as delimiters, as in:
Input:
or:
or:
Output:
1,2,3,4 |
Note that the order of the elements of a sequence is significant. For
example, if B:=(5,6,3,4) and C:=(3,4,5,6), then
B==C returns false.
(A value can be assigned to a variable with the := operator;
see Section 5.4.1.
Also, == is the test for equality; see
Section 6.1.2.)
Note also that the expressions seq[…] and
seq(…) are not the same (see Section 6.39.2 for
information on seq(…)). For example,
seq([0,2])=(0,0) and seq([0,1,1,5])=[0,0,0,0,0]
but
seq[0,2]=(0,2) and seq[0,1,1,5]=(0,1,1,5)
See Section 6.39 for operations on sequences.
