Bold

   The single character occurrence of the Bold flag (*) causes
   the next character to be printed in boldface; that is, to be
   overstruck once. You can cause characters to be overstruck more
   than once by using the /BOLD=number qualifier when processing
   the file with the RUNOFF command. Pairing the bold flag with the
   uppercase flag (^*) turns on the bolding until the lowercase/bold
   pair (\*) is encountered.
