Summary

Function: string llList2String( list src, integer index );

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.
