|
Returns a nonempty list of strings.
|
|
The first element is an implementation-specific
|
|
name for the running top-level program. The remaining elements are command-line
|
|
arguments according to the operating system’s conventions.

<div align=left><tt>(<a name="node_idx_848"></a>exit<i> obj</i>)</tt> procedure </div>
|
|
<p>
|
|
Exits the running program and communicates an exit value to the
|
|
operating system. If no argument is supplied, the <tt>exit</tt>
|
|
procedure should communicate to the operating system that the program
|
|
exited normally. If an argument is supplied, the <tt>exit</tt> procedure
|
|
should translate the argument into an appropriate exit value for the
|
|
operating system. If <i>obj</i> is <tt>#f</tt>, the exit is assumed to
|
|
be abnormal.
