<div class="markdown_content"><p><em>Originally created by:</em> Fx64</p> <p>Hallo Tiak,</p> <p>ich denke es genügt nicht den Typ anzugeben:</p> <p>phelp := phelp + SIZEOF(REAL);</p> <p>ändere mal den sizeof</p> <p>phelp := phelp + SIZEOF(Recieved1);</p> <p>Viele Grüsse</p></div>

<div class="markdown_content"><p>Hallo Tiak,</p> <p>unabhängig von der indirekten Adressierung geht das, was du vorhast gar nicht, denn die Variablen Recieved1... sind vom Typ Real (also 4 Byte) und diese willst du indirekt Bytevariablen zuweisen. </p> <p>Gruß Norbert</p></div>
