Attribute for <FORM ...>
TARGET ="_blank" |"_parent" |"_self" |"_top" |frame name

TARGET indicates which frame in a set of frames to send the results to, and works just like <A TARGET="...">. This attribute can be used so that the form is always visible even as the form results are displayed and redisplayed.

this code	produces this
<FORM TARGET="TargetFrame" ACTION="../cgi-bin/html/mycgi.pl">	this page

<FORM onSubmit="..."> >>>
