For consistent pagination, WordPerfect had an option to "suppress the extra
line at the top of the page" if a one of the two lines between paragraphs
carried over to the next page.
Does Word offer that feature?
If you create blank space between paragraphs by hitting enter twice, no Word
will not suppress it, because you have deliberately created a paragraph
which Word respects as it does other paragraphs. An empty paragraph is
subject to the same rules. (Click ¶ on the standard toolbar to see your
empty paragraphs as ¶, Find and Replace, click More, use the Special menu
will let you replace 2 consecutive ¶s with 1, to eliminate these.)
You should use the Space After setting (via Format | Paragraph) to create
blank space between paragraphs, and then Word should suppress it when
necessary. Others may have more to add.
Since you are more familiar with Word Perfect than Word, you may find these
