This means that HTML code after <VAR
CLASS="literal"
>// ?></VAR
> WILL be printed:
?> skips out of the PHP mode and returns to HTML mode, and
<VAR
CLASS="literal"
>//</VAR
> cannot influence that.
If <A
HREF="ini.sect.language-options.html#ini.asp-tags"
>asp_tags</A
> configuration directive
is enabled, it behaves the same with <VAR
CLASS="literal"
>// %></VAR
>.
