UserTag foo <<EOR
sub {
	...
	some code
	...
	$debug=1;
	...

if($debug) {
::logGlobal("my string $my_var");
}
	...

Anything passed to logGlobal will show up in the file error.log (at least
on Unix...).  I actually run MV in normal mode and debug with logGlobal.

Again, if you use Unix, I run 'tail -f error.log' in a separate window.
That way, I see all the dumps to the log as they happen.  Very useful.  If
you use NT, YMMV.

Best,
