&quot;Group numbers are assigned by the order of occurrences of the opening bracket of a group and counted starting from 0 by step 1.&quot;<br />
As a result the the whole expression as such cannot be addressed (this is illustrated in the 1st example too, where the 1st subgroup is addressed with groupno 0).<br />
<br />
This addressing is a bit confusing since e.g. for the posix C definition the index starts with 1 and 0 means that no subgrouping is applied i.e. index 0 addresses the whole expression.<br />
There are the following issues to be clarified:<br />
- clarification that TTCN regexp differs from POSIX implementation of regexp (to make clear that there is a difference)<br />
- example and clarification how to address the whole expression or what happens when an expression has no subgroup (currently that seems even not possible since index 0 would refer to a non-existing subgroup)<br />
- As alternative the index could made optional (e.g. in &quot;template (omit) integer groupno := omit&quot;) with omit for the top-level expression<br />
