Summary
Function: string llList2String( list src, integer index );188 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Returns a string that is at index in src.
• list | src | |||
• integer | index |
index supports negative indexes.
If the type of the entry at index in src is not a string it is typecast into a string.
If index is out of range it returns a null string.
Specification
Index | Positive | Negative |
---|---|---|
First | 0
|
-length
|
Last | length - 1
|
-1
|
Indexes
- Positive indexes count from the beginning, the first item being indexed as
0
, the last as(length - 1)
.
- Negative indexes count from the far end, the first item being indexed as
-length
, the last as-1
.
Caveats
- If index is out of bounds the script continues to execute without an error message.
Examples

Notes
To convert a string of hex nybbles to integer, call llList2String and then type cast that string result to integer.
To convert that integer back to a string of hex nybbles, call hex.
