Strings
String literals are used to represent text. A string consists of zero or more
characters and can include numbers, letters, spaces, and punctuation. An
empty string ("") contains no characters and evaluates to false in an
expression, whereas a non-empty string evaluates to true. Double quotes
surround a string, and some standard backslash (\) escape sequences are
supported.
Escape Sequences
These are the available escape sequences in CSL:
String Represented text
"Quote: \"This is a string
literal.\""
Quote: "This is a string
literal."
"256"
256 **Note that this does not represent the
integer 256, but only the characters that make up the
number.
"abcd!$%&*" abcd!$%&*
"June 26, 2001" June 26, 2001
"[ 1, 2, 3 ]" [ 1, 2, 3 ]
