18.4.2.7 Assigning a computed title
If titles for your HTML pages can be determined based on the value of a macro variable, or on values obtained by expanding a macro, you can assign the macro or macro variable to the [HTMLOptions]Title keyword.
For example, to provide a page title that consists of the FrameMaker source file name followed by an integer that increments for each HTML file generated:
<$$_basefile><$$PgNumber++ as %-0.3d>
Any other title specification overrides a computed [HTMLOptions]Title value.
