4405 In particular, if (*THEN) is present in a group that is called as a
4406 subroutine, its action is limited to that group, even if the group does
4974 This is an example of an "atomic group", details of which are given
4975 below. This particular group matches either the two-character sequence

6044 Note that a possessive quantifier can be used with an entire group, for
6051 simpler forms of atomic group. However, there is no difference in the
6052 meaning of a possessive quantifier and the equivalent atomic group,
6069 atomic group is the only way to avoid some failing matches taking a
6088 group, like this:
6207 Back references of this type cause the group that they reference to be
6208 treated as an atomic group. Once the whole group has been matched, a

6506 The first part of the pattern is a DEFINE group inside which a another
6507 group named "byte" is defined. This matches an individual component of
6510 condition. The rest of the pattern uses references to the named group

7011 appears inside an atomic group, its effect is confined to that group,
7012 because once the group has been matched, there is never any backtrack-
