<br />
For normal alt statements, the possibility to de-inline them by defining them as a teststep and then referencing them from multiple places exists, while for interleave, this is not possible. That means that if the same interleave statement is needed in multiple places, it needs to be copied which is bad for code maintenance and readability.<br />
<br />
As a workaround, at the moment, the interleave statement can be put into a function, but then this cannot be used in the place of altsteps in the event-part of an alt-statement, but only as a new top-level interleave.<br />
<br />
For better compositionality and consistency, we thus propose to allow to define interleave altsteps and to allow to use such altsteps wherever a normal altstep reference is allowed, i.e.<br />
<br />
altstep I() interleave {<br />
&lt; local variable declarations that live during the duration of this block &gt;<br />
[] ... <br />
[] ...<br />
}<br />
<br />
alt {<br />
[] I() { ... }<br />
[] ... <br />
}<br />
<br />
The syntactic changes to the language would be minimal and fully backward compatible.</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;7619.docx (101,443) <span class="italic">13-12-2017 12:43</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3727&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7619-2.docx (161,943) <span class="italic">20-07-2018 08:59</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3782&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">16-02-2017 14:59</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">06-06-2017 14:38</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;
