    <blockquote type="cite">That's actually a FPC compiler bug:

      <pre class="code highlight" lang="plaintext"><span>    procedure WriteProperty(Path: String; Instance: TObject;</span>

<span>                            PropInfo: Pointer; DefInstance: TObject = nil;</span>

<span>                            const OnlyProperty: array of String);</span>

</pre>

    </blockquote>

    <br>

    <br>

    then what is the correct syntax?<br>

    <br>

    The link suggests there needs to be a default value for OnlyProperty

    (and I would have expected that too).<br>

    <br>

    But FPC does reject *any* default. It reject the = sign itself, if

    any is added.<br>

    <br>

    So what is the correct syntax?<br>
