Unless otherwise specified, an equivalency is implied for each item in the *filter-list*.

For numeric group codes (integers, reals, points, and vectors), you can specify other relations by including a special -4
group code that specifies a relational operator. The value of a -4 group code is a string indicating the test operator to
be applied to the next group in the *filter-list*.

The following selects all circles with a radius (group code 40) greater than or equal to 2.0:

(ssget "X" '((0 . "CIRCLE") (-4 . ">=") (40 . 2.0)))

The possible relational operators are shown in the following table:

The use of relational operators depends on the kind of group code value you are testing:

- All relational operators except for the bitwise operators ("&" and "&=") are valid for both real- and integer-valued groups.
- The bitwise operators "&" and "&=" are valid only for integer-valued groups. The bitwise AND, "&", is true if ((
*integer_group*&*filter*) /= 0)—that is, if any of the bits set in the mask are also set in the integer group code. The bitwise masked equals, "&=", is true if ((*integer_group*&*filter*) = filter)—that is, if all bits set in the mask are also set in the*integer_group*(other bits might be set in the*integer_group*but are not checked). - For point group codes, the
*X*,*Y*, and*Z*tests can be combined into a single string, with each operator separated by commas (for example, ">,>,*"). If an operator is omitted from the string (for example, "=,<>" leaves out the*Z*test), then the “anything goes” operator, "*", is assumed. - Direction vectors (group code 210) can be compared only with the operators "*", "=", and "!=" (or one of the equivalent “not equal” strings).
- You cannot use the relational operators with string group codes; use wild-card tests instead.
