A string is text data. The length of a string is only limited by available script memory. String values are enclosed in double quotes when defined in LSL text. Any character may be used in a string though some will need to be escaped.

Strings can be concatenated using the + operator.

Escape codes
Substring Replaced with
\t four spaces
\n new line
\" double quote
\\ backslash

String examples:

"Hello Avatar!"
"Yes"
"No"
"It's 10 o'clock."
"I am 21 years old!"
"Help " + "me"
EOF
//The following two strings have the same value.
"I scream,\nyou scream,\nwe all scream,\nfor ice-cream!"
"I scream,
you scream,
we all scream,
for ice-cream!"

Note: escape codes (listed above) are translated when the script is compiled, and not while it's running. The result: only strings that are inside your script when it is compiled will get, say, \n turned into a "new line" character. Text you read in from a notecard, chat, http, etc, will not be checked for escape codes -- that same \n typed in a notecard doesn't automatically turn into a "new line" character in any case. You'll have to do that yourself, if you really really need it for some reason.
