As strife pointed out in the 1.6 Feature Feedback forum llDeleteSubString does not currently work correctly in 1.5. It seems most likely that it has never worked correctly.
The problem seems to be with the use of any negative index. The negative index should count back from the end of the list and otherwise behave normally. In 1.5 the negative index counts past the end of the list. For example an index of -5 on a list of length 10 would be interpreted as an index of 15 rather than 5.
If this were to get fixed, would it break your existing scripts?

I don't think so, I tend to find the index and delete it as a positive number. I am sure there are others who will find it more awkward though...

No, I don't think so. I ran into this problem myself, and I think I submitted a bug report on it. I don't think llDeleteSubString was the only function that had this problem with negative indices -- check llDeleteSubList too, for starters. I worked around it by figuring out positive indices to use, so this wouldn't mess me up.

Won't affect my scripts. I avoid using the negative wrap-around features of functions like this since it just confuses what I want to do.

i don't expect it will break my scripts, i don't use llDeleteSubString often, and usualy not with negative indices. But i'm tickled it's getting fixed

Oh. It worked that way? I was trying to figure out what Strife had meant by that. No, I don't think it will break any of my scripts either.

The new preview, which should be open shortly, has the 'fixed' code for llDeleteSubString. If anyone has some time to test some existing scripts and play around with it on the preview I would greatly appreciate the feedback.
Also, please pass the word around to any scripters who may not visit this forum.

Now that preview is back up with the fixed code for llDeleteSubString it would be great if I could get some more feed back from anyone who has a chance to check out old or new content as of this patch.

It is noted in the wiki that this same problem exists with llInsertString().
Maybe that could/should be fixed at the same time.
Cheers,
JL
