<h3>
paxScript Demo. Cross-language Programming. Using paxPascal classes in paxJavaScript scripts.
</h3>
<hr>

Let's consider a paxPascal script:


<blockquote>
<pre>
<font color="blue"><b>program</b></font> Demo;
<font color="blue"><b>type</b></font>
  TRandomPoint = <font color="blue"><b>record</b></font>
    X: Integer = Random(100);
    Y: Integer = Random(100);
    <font color="blue"><b>function</b></font> TRandomPoint(): TRandomPoint;
    <font color="blue"><b>begin</b></font>
      result := Self;
    <font color="blue"><b>end</b></font>;
  <font color="blue"><b>end</b></font>;

   TPascalClass = <font color="blue"><b>class</b></font>(TObject)
   <font color="blue"><b>private</b></font>
     fProp: Integer = 10;
    <font color="blue"><b>public</b></font>
     <font color="blue"><b>constructor</b></font> Create;
     <font color="blue"><b>function</b></font> TPascalClass: TPascalClass; // <i>to use it in paxJavaScript or paxC</i>
     <font color="blue"><b>property</b></font> Prop: Integer read fProp;
   <font color="blue"><b>end</b></font>;

<font color="blue"><b>constructor</b></font> TPascalClass.Create;
<font color="blue"><b>begin</b></font>
  <font color="blue"><b>inherited</b></font>;
<font color="blue"><b>end</b></font>;

<font color="blue"><b>function</b></font> TPascalClass.TPascalClass: TPascalClass;
<font color="blue"><b>begin</b></font>
  result := Self;
<font color="blue"><b>end</b></font>;

<font color="blue"><b>begin</b></font>
<font color="blue"><b>end</b></font>.
</pre>
</blockquote>

You can use TRandomPoint, TPascalClass types in paxJavaScript scripts. For example:

<blockquote>
<pre>
x = <font color="blue"><b>new</b></font> Demo.TPascalClass();
<font color="blue"><b>print</b></font> x.Prop;
p = <font color="blue"><b>new</b></font> Demo.TRandomPoint();
<font color="blue"><b>print</b></font> p.X;
<font color="blue"><b>print</b></font> p.Y;
</pre>
</blockquote>
