/BREAK=break-character
Selects the break character. The break character is used to
generate a break on lines that expect a break rather than a
carriage return. To generate a break, press Ctrl/break-character.
The break character can be any ASCII character between @ and
z, except C, M, Q, S, Y, or the left bracket ([). You cannot
select a character currently defined as either the command
character (see the description of the /COMMAND=command-character
qualifier) or the escape character (see the description of the
/ESCAPE=escape-character qualifier).
The ASCII characters between @ and z include the alphabetic
characters in both upper and lower cases, the at sign (@), the
backslash (\), the right bracket (]), the circumflex (^), the
underscore (_), and the grave accent (`).
By default, the break character is the right bracket (]).
