llList2String

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.

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.
