<H3><A NAME="M4">DESCRIPTION</A></H3>
|
||
|
|
This command is typically invoked inside the body of a looping command
|
||
|
|
such as <B><A HREF="../TkCmd/for.htm">for</A></B> or <B><A HREF="../TkCmd/foreach.htm">foreach</A></B> or <B><A HREF="../TkCmd/while.htm">while</A></B>.
|
||
|
|
It returns a TCL_BREAK code, which causes a break exception
|
||
|
|
to occur.
|
||
|
|
The exception causes the current script to be aborted
|
||
|
|
out to the innermost containing loop command, which then
|
||
|
|
aborts its execution and returns normally.
|
||
|
|
Break exceptions are also handled in a few other situations, such
|
||
|
|
as the <B><A HREF="../TkCmd/catch.htm">catch</A></B> command, Tk event bindings, and the outermost
|
||
|
|
scripts of procedure bodies.
