This feature goes back through several versions of Word and WordPerfect and
problably any other early word processing program you can imagine.  I have
not had any use for it in many versions, but someone asked me the other day
and I was stumped.  I do remember using this feature to make sure license
plate numbers, id, social security number and the like did not break on a
line.  I suggested kerning or orphan programming, but neither was
satisfactory.  Any help would be appreciated.
