Newbie question on available IE data and staus flags in Perl

[DG]

Hello and thanks for the help,

At the end of this message is a snip of code that I'm using to control IE.
It gets the Busy status of IE by using:
$stat=$BROWSER->{Busy};
It also gets the HTML data by using:
$mystring1= $body->{innerHTML}; #get the HTML data from browser
$mystring2= $body->{innerTEXT}; #removes all HTML commands leaving only
the text

My question: besides {Busy}, {innerHTML}, and {innerTEXT}, what other status
and data flags are available for IE 6.0? (I'm don't know where to look up
this info. A Google search didn't yield anything for me.) Right now, I'm
interested in error and warning status flags (every once in a while, the
browser returns nothing, and I'd like to handle it cleanly), but I'd also
like the rest of the flags for future use.

thanks for the help,
DG
