Hi Gordc,
Having the heading and the body text on the same line is not normal, but it's not especially unusual either. And it's quite easy to achieve in Word 2003 & later, via a Style Separator. Simply create two separate paragraphs - one in the Heading Style for the content that's to appear in the TOC and another for the remainder of the paragraph. When you've done this, simply click anywhere in the Heading Style paragraph and press Ctrl-Alt-Enter.

Time to upgrade??
