<span class="style3">// This is an example DFL file. Using CLI, you can run this file like PHP would run a .php file.
// Commented lines are prefixed with # or //. These lines are not processed, and are ignored like
// whitespace.</span>

<span class="style3">// First, let's define a method for downloading a file from a remote webserver.</span>
<span class="style3">
// First, we "build" the method.</span>
<span class="style4">MethodBuild</span> <span class="style5">Download</span>
<span class="style3">
// Next, we append to the method DFL code. This code will be executed when we call Download.
// The first line will be a function to download data from another server.</span>
<span class="style4">MethodAppend</span> <span class="style5">Download</span> <span class="style4">FNC</span> <span class="style5">download</span> <span class="style4">STR</span> <span class="style5">return implode('', file($args));</span>

<span class="style3">// Now let's define a variable called "return", and make it equal to the return of the execution of the
// function "download". We will pass an argument (variable args)</span>
<span class="style4">MethodAppend</span> <span class="style5">Download</span> <span class="style6">VAR</span> <span class="style5">return</span> <span class="style4">RUN</span> <span class="style5">download</span> <span class="style4">VAR</span> <span class="style5">args</span>
<span class="style3">
// Now, let's make the method return the "return" variable.</span>
<span class="style4">MethodAppend</span> <span class="style5">Download</span> <span class="style4">RET</span> <span class="style4">VAR</span> <span class="style5">return</span>

<span class="style3">###################</span>

<span class="style3">// Now let's work on the main script. The method is basically a function composed of DFL statements.
// Let's create a regular function to "echo" content.</span>

<span class="style4">FNC</span> <span class="style5">echo</span> <span class="style4">STR</span> <span class="style5">echo $args;</span>

<span class="style3">// Now, let's make a variable called "url". We'll store the URL we wish to download content from within
// that variable.</span>

<span class="style4">VAR</span> <span class="style5">url</span> <span class="style4">STR</span> <span class="style5">http://cmyip.com/</span>
<span class="style3">
// Now, let's run the "echo" function, passing the "url" variable as an argument which will be printed
// to the output buffer (echo'd)</span>

<span class="style4">RUN</span> <span class="style5">echo</span> <span class="style4">VAR</span> <span class="style5">url</span>
<span class="style4">RUN</span> <span class="style5">echo</span> <span class="style4">STR</span> <span class="style5"> --> Being downloaded...</span>

<span class="style3">// Let's make a function called newline which will return a newline.</span>

<span class="style4">FNC</span> <span class="style5">newline</span> <span class="style4">STR</span> <span class="style5">return newline();</span>

<span class="style3">// Let's print a newline.</span>

<span class="style4">RUN</span> <span class="style5">echo</span> <span class="style4">RUN</span> <span class="style5">newline</span>

<span class="style3">// Let's download the content of the page and store it in a variable.</span>

<span class="style4">VAR</span> <span class="style5">content</span> <span class="style7">Download</span> <span class="style4">VAR</span> <span class="style5">url</span>

<span class="style3">// Let's echo the content.</span>

<span class="style4">RUN</span> <span class="style5">echo</span> <span class="style4">VAR</span> <span class="style5">content</span>
