CW(l)
CW (l)
.OW Start of text to be set in the CW font; .CW causes a
break; it can take precisely the same options, in precisely
the same format, as are available on the cw command
line .
• CN End of text to be set in the CW font; .CN causes a break;
it can take the same options as are available on the cw �l
command line .
• CD Change delimiters and/or settings of other options; takes
the same options as are available on the cw command
line .
• CP argl argB arg9 ••• argn
All the arguments (which are delimited like troff macro
arguments) are concatenated, with the odd-numbered
arguments set in the CW font and the even-numbered ones
in the prevailing font .
• PC argl argB arg9 ••• argn
Same as .CP, except that the even-numbered arguments
are set in the CW font and the odd-numbered ones in the
prevailing font.
The .CW and .CN requests are meant to bracket text (e.g., a program
fragment) that is to be typeset in the CW font "as is." Normally,
cw operates in the transparent mode. In that mode, except
for the .CD request and the nine special four-character names
listed in the table above, every character between .CW and .CN
request lines stands for itself. In particular, cw arranges for �. ]
periods (.) and apostrophes ( ') at the beginning of lines, and
backslashes (\) everywhere to be "hidden" from troff. The transparent
mode can be turned off (see below), in which case normal
troff rules apply; in particular, lines that begin with . and ' are
passed through untouched (except if they contain delimiters-see
below). In either case, cw hides the effect of the font changes generated
by the .CW and .CN requests; cw also defeats all ligatures
(fi, ff, etc.) in the CW font.
The only purpose of the . CD request is to allow the changing of
various options other than just at the beginning of a document.
The user can also define delimiters . The left and right delimiters
perform the same function as the .CW j.CN requests; they are
meant, however, to enclose CW "words" or "phrases" in running
text (see example under BUGS below). Cw treats text between
delimiters in the same manner as text enclosed by .CW j.CN
pairs, except that, for aesthetic reasons, spaces and backspaces
inside .CW j.CN pairs have the same width as other CW characters,
while spaces and backspaces between delimiters are half as
wide, so they have the same width as spaces in the prevailing text ·�
(but are not adjustable). Font changes due to delimiters are not
hidden.
Delimiters have no special meaning inside .CW j.CN pairs.
