<H2>LASTERR Retrieve Last Error Message
</H2>
<P>
Section: <A HREF=sec_flow.html> Flow Control </A>
<H3>Usage</H3>
Either returns or sets the last error message. The
general syntax for its use is either
<PRE>
msg = lasterr
</PRE>
<P>
which returns the last error message that occured, or
<PRE>
lasterr(msg)
</PRE>
<P>
which sets the contents of the last error message.
<H3>Example</H3>
Here is an example of using the <code>error</code> function to
set the last error, and then retrieving it using
lasterr.
<PRE>
--> try; error('Test error message'); catch; end;
--> lasterr
ans =
Test error message
</PRE>
<P>
Or equivalently, using the second form:
<PRE>
--> lasterr('Test message');
--> lasterr
ans =
Test message
</PRE>
<P>
