Im realy lost now !

It seems POP makes up its own mind when to POP an element or just pop away.. ;-)
( syntax: (pop str [int-index] [int-length]))

"2"

I realy did expect to see an "8" and not a "890" here...

Looks like it may be trying to pop n items from position n when n+n > stringlength
as (V9.0)

"12345"

"45"

"12345"

"3"

"1234567"
> (pop t 4)
"567"
> (setq t "1234567890")
"1234567890"
> (pop t 4)
"5"

Can't see immediately from code in nl-liststr.c why this should be.
