What is the first language to have inline commands in HTML code?

I'm learning PHP. The PHP has inline commands in HTML code to produce dynamic HTML output.

<div>
    <?php echo 'hello world'; ?>
</div>

In the Java and .NET world, there are similar syntaxes to have commands in HTML.

What is the first language or platform to ha开发者_如何学JAVAve this kind of syntax, having dynamic code embedded in HTML code and generating dynamic HTML code?

AOLserver supported inline Tcl in that way back in 1994. For an example of how it looks, see the Writing Your First ADP tutorial. Also, Phil Greenspun has an excellent Introduction to AOLserver written in 1999.

The first I have come across have been Server-Side Includes. They have been introduced in the NCSA web server version 1.2, in 1994.

Before that, they had a simpler system using INC SRV tags, like <inc srv "|date"> to include the current date. The oldest reference to that I could find was a question on a mailing list, dating back to November 1993.
