\subsection return-description Description The \c return builtin is
|

used to halt a currently running function. It is usually added inside
|
|
of a conditional block such as an <a href="#if">if</a> statement or a
|
|
<a href="#switch">switch</a> statement to conditionally stop the
|
|
executing function and return to the caller.
|
|
|
|
- \c STATUS is the return status of the function. If unspecified, the status is set to 0.
