Tag-based Syntax
As an alternative to the AMPscript block syntax, the HTML script tag is also supported. This syntax can be beneficial when developing in both Server-Side JavaScript (SSJS) and AMPscript, as it provides a standardized syntax for interpreting both server-side scripting languages.
Additional runat and language attributes must be included in the opening script tag for the containing code to be interpreted as AMPscript, as indicated in the example below.
<script runat="server" language="ampscript">
/* AMPscript code */
</script>
