:CHAR abc[] "Say \34Hello!\34 to her"
which would be converted to
Say "Hello!" to her
Less cryptic methods include:
:CHAR abc[] <Say "Hello!" to her>
def[] "Say \"Hello!\" to her"
The Back Slash (\)
The back slash character ( \ ) is a special one within strings. It serves as the trig-
ger for an escape sequence, which simply means that the decimal or hexidec-
imal value following the
\ is to be converted into a character. If you really
want a back slash and not an escape sequence, then use two back slashes. Ex-
amples are shown in Table 22-6.
Following a \ inside of a string constant, LPL expects to find one of the fol-
lowing:
¥ up to 3 digits
Three digits making a number in the range 0É255 (e.g. \10 \255).
¥
A hex value
An x or X, followed by up to two hexidecimal digits (0ÉF) (e.g. \x0d \xff)
¥ another back slash \
(e.g. \\)
