</cmdsynopsis>
<para>If the break command is used in a function, function execution is
terminated immediately. Further commands of the function are not
processed. Normally, all nested invocations of complex functions
are left. An optional integer number
<replaceable>levels</replaceable>
may be given to break out of the given number of nested functions
and continue execution of a higher level function.
The
<emphasis remap='B'>Break</emphasis>
command always has the return code -2. Example:</para>
<programlisting>
<fvwmref cmd="AddToFunc"/> PickWindowRaiseAndDeiconify
+ I <fvwmref cmd="Pick"/>
+ I <fvwmref cmd="TestRc"/> (Error) Break
+ I <fvwmref cmd="Raise"/>
+ I <fvwmref cmd="Iconify"/> off
</programlisting>
