15.6.1 Referencing individual string elements<br />
It is not allowed to reference individual string elements inside templates or template fields. Instead, the substr<br />
function (see clause C.4.2) shall be used. <br />
<br />
should be removed from the standard. The index notation is problematic in the same cases as the substr function would be problematic (i.e. if there are matching mechanisms inside the template before the given index or index-range), so why would one be allowed and one not?<br />
<br />
This is just a confusing rule and should be removed as it serves no purpose.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Tags</td><td class="print" colspan="5">No tags attached.</td></tr><tr class="print"><td class="print-category">Relationships</td><td class="print" colspan="5"><table border="0" width="100%" cellpadding="0" cellspacing="1"><tr><td class="print"><span class="nowrap">related to</span>&#160;</td><td class="print">0008067</td><td class="print">closed&#160;</td><td class="print"><span class="nowrap"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></span>&#160;</td><td class="print">Postfix value notation for templates&#160;</td></tr></table></td></tr><tr class="print"><td class="print-category">Attached Files</td><td class="print" colspan="5"><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-210907.docx (72,608) <span class="italic">07-09-2021 14:39</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4004&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-2.docx (100,024) <span class="italic">09-09-2021 09:15</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4008&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-3.docx (111,431) <span class="italic">10-11-2021 07:52</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4046&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-4.docx (138,520) <span class="italic">11-11-2021 12:47</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4054&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-5.docx (104,805) <span class="italic">11-11-2021 15:00</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4056&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR8006-6.docx (145,910) <span class="italic">12-11-2021 10:39</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=4059&amp;type=bug</td></tr><tr><td class="print-spacer" colspan="6"><hr size="1" /></td></tr><tr><td class="form-title">Issue History</td></tr><tr class="print-category"><td class="row-category-history">Date Modified</td><td class="row-category-history">Username</td><td class="row-category-history">Field</td><td class="row-category-history">Change</td></tr><tr class="print"><td class="print">17-02-2021 12:55</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=508">Jacob Wieland - Spirent</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">23-03-2021 16:16</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Project</td><td class="print">TTCN-3 Change Requests =&gt;

				I was not happy with just removing the rules as it gave no guidance what to do when the template contains something different than a specific value. So I changed the section in a similar way how the substr function works. <br />
<br />
But it would cernainly be possible to do more than that, e.g. index applied to AnyValue could yield '?'B or pattern &quot;?&quot;. We could also return a template instead of a value (e.g. var hexstring v_hex := 'AB?CD'H; return v_hex[2]; would return '?'H), various metacharacters matching a single value (such as \s, \n etc.) could count as a single item allowing us to return a pattern.<br />
<br />
Please let me know if the proposed changes are sufficient or we need something more elaborate.			</td>

				I like the idea of being able to deconstruct string patterns element-wise. Maybe it would be less restrictive if the result of accessing a pattern element would also yield a pattern and that all concatenable matching elements are seen as a single element:<br />
<br />
- meta characters count as a single element and are mapped to their character.<br />
- AnyValue and AnyValueOrNone count as a single element<br />
- character groups ([a-z]) count as a single elemnet and are mapped to a pattern containing them<br />
- repeated elements (X#(a,b)) count as a single element <br />
- disjunction elements (X|Y) count as a single element<br />
- reference elements ({&lt;name&gt;}) count as a single element			</td>

				I think we should discuss the details first. This kind of a change would probably require a change of the rules for the substr function (and maybe the replace function) so that they would use the same set of rules.<br />
<br />
My proposal should be changed anyway as I realized that the rules are written just for the RHS of an assignment (without actually saying that!) and we would need guidance for the LHS as well.<br />
<br />
As regards the &quot;unpattern&quot; operation, I generally agree that is would be a useful feature. I think we could overload the valuof operation, in which case we wouldn't need any changes on the syntax level and new keywords. But we should create a separate CR for that.			</td>

6) In the EXAMPLE, the result for the character group shall be pattern &quot;[a-z]&quot;<br />
<br />
7) IN the table in the indexing column, the 3 cases of Without the preceding expression need to be changed to Including the preceding expression (as #n, #() and + constructions on their own do not constitute a proper pattern element without the expression they are applied to)<br />
<br />
8) In rule e) the to-pattern conversion should add escape backslashes for all special characters contained in the value before adding the pattern keyword.<br />
<br />
<br />
There also are some typos: 3 times ispresent instead of ifpresent<br />
