<div class="markdown_content"><p>Same question here...</p> <p>From my tests it seems also that if I try to fill the queue it gives the "Max size exceeded" error with the exact size of the array.</p> <p>So it seems that there is no need to have an underlying array 2 times the max size, but I'm concerned with possible memory overflows...</p></div>

<div class="markdown_content"><p><strong>Hello</strong>,</p> <p>in the <em>SimpleQueueExample</em> there is the following <em>NOTEs</em>.<br/> <code>aElements : ARRAY[0..9] OF COL.IElement; // Create an array of IElements for a static queue. NOTE: The size must be 2 times larger than the maximum number of used elements.</code></p> <p><code>queue : COL.Queue := (paElements := ADR(aElements), udiMaxElements := 10); // Created a static queue. NOTE: Static created elements of this queue will be online change safe.</code></p> <p>What does <code>The size must be 2 times larger than the maximum number of used elements.</code> exactly mean?</p> <p>Is it true?</p> <p>Thanks for the help in advance.</p></div>
