2.3.7. - String Constants
Strings are delimited by pairs of single or double quotes. The following escape sequences, introduced by a backslash, can be included within strings to represent certain special characters:
\a |
attention, audible alert (bell) |
\b |
back space |
\f |
form feed |
\n |
newline |
\r |
carriage return |
\t |
horizontal tab |
\\ |
backslash |
\' |
single quote |
\" |
double quote |
\ooo |
octal code |
\[xx] |
tty control code |
Tty control codes are only recognized when embedded in strings passed to spec's built-in functions
tty_move()
and
tty_fmt().
The recognized strings for
xx
are described in the description of the
tty_cntl()
function
2.4.2.5
For any other character
x,
\x\ooo\033 represents the
escape
character.
A character string can be continued over more than one line by using a
\
at the end of a line.
On the other hand,
new lines not preceded with a
\ are inserted literally into the string.
