On the RHS, it seems quite obvious - an error shall be generated. On the LHS, there are two options: either produce an error as well or allow index 0 to create a string with length 1 (that would be consistent with expansion of an empty string). I would prefer the first option.<br />
<br />
Proposal: add the following restriction to the section 6.1.1.1:<br />
Referencing an identified element of an uninitialized or omitted string field or value on the right or left hand side of an assignment shall cause an error.</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"></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;CR-6864-150804-V1.docx (59,097) <span class="italic">04-08-2015 14:48</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3230&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR6864_resolution_v2.docx (78,642) <span class="italic">03-11-2015 14:29</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3355&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">14-01-2015 08:38</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=659">Tomas Urban</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">14-01-2015 14:10</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">Note Added: 0012673</td><td class="print"></td></tr><tr class="print"><td class="print">14-05-2015 10:09</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=127">Gyorgy Rethy</a></td><td class="print">Target Version</td><td class="print"> =&gt;
