|Specifies how many stack frames of [http://en.wikipedia.org/wiki/Tail_call tail-calls] are allowed on the stack at any time. When this limit is reached, tail-call optimization takes place and some call frames are eliminated. The feature can be turned off by setting the value to {{Code|-1}}.

===WITHDB===
{{Mark|Introduced with Version 9.3.}}
{| width='100%'
|-
| width='120' | '''Signature'''
|{{Code|WITHDB}}
|-
| '''Default'''
|{{Code|true}}
|-
| '''Summary'''
|By default, URIs specified in the [[Databases#XML Documents|fn:doc]] and [[Databases#XML Documents|fn:collection]] functions will also be resolved against existing databases. If {{Function|Database|db:open}} is consistently used to access database documents, it is recommendable to disable this option:
* Access to local and external resources will be faster, as the database lookup will be skipped.
* No locks will be created by the two functions (see [[Transaction Management#Limitations|limitations of database locking]] for more details).
