The following example shows how to set a special document title for Windows Help:
!ifdest [win] !docinfo [title] The Windows Help to !else !docinfo [title] The guide to !endif
The !ifndest command is related to !ifdest. But !ifndest will check if you do not convert to the given destination format. Thus you can write the upper example this way, too:
!ifndest [win] !docinfo [title] The guide to !else !docinfo [title] The Windows Help to !endif
You can pass more than one abbreviation to the query command. If you do so the query returns a true value if one or more abbreviations match the current destination format. The next example shows how to set a special document title for hypertext formats:
!ifdest [win,html,stg,htag] !docinfo [title] The hypertext to !else !docinfo [title] The guide to !endif
