I don't know if you use the ROSA-Applet in conjunction with the
CGIBinary Mapserver or some kind of MapScript. However, 
xxx_NAME should be a variable name to be set to xxx_VALUE,
e.g.
 <PARAM NAME="TB_BUT_zoomout_NAME" VALUE="zoomdir">
 <PARAM NAME="TB_BUT_zoomout_VALUE" VALUE="-1">

or 
 <PARAM NAME="TB_BUT_pquery_NAME" VALUE="mode">
 <PARAM NAME="TB_BUT_pquery_VALUE" VALUE="nquery">

You can find a simple template using the ROSA-Applet under:
ftp://ftp.intevation.de/users/frank/mapserver/rosa-sample.zip

and a list of links to more details under
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?CGIMapServer

Of course there is always the original doumentation under:
