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.
