Hi Steve,
OK, I added the QUERYMAP section and changed the URL:
http://localhost/cgi-bin/mapserv?map=/NWPL_CRREL/MLRA/mlra.map
<http://localhost/cgi-bin/mapserv?map=/NWPL_CRREL/MLRA/mlra.map&qlayer=coe_m
&mode=itemnquerymap&searchmap=true&layer=states&mapext=-91+34+-89+49&mapsize
=600+400&qitem=MLRARSYM&qstring=(%22%5bMLRARSYM%5d%22%20in%20%22102A,102B,10
2C,103,104,105,106,107A,107B,108A,108B,108C,108D,109,110,111A,111B,111C,111D
,111E,112,113,114A,114B,115A,115B,115C%22)>
&qlayer=coe_m&mode=itemnquerymap&searchmap=true&layer=states&mapext=-91+34+-
89+49&mapsize=600+400&qitem=MLRARSYM&qstring=("[MLRARSYM]"%20in%20"102A,102B
,102C,103,104,105,106,107A,107B,108A,108B,108C,108D,109,110,111A,111B,111C,1
11D,111E,112,113,114A,114B,115A,115B,115C")
Now I get the map with some of the items highlighted in yellow, and the rest
green:

Just add a querymap object to your mapfile, like so:
QUERYMAP
STATUS ON
END
Then change your URL to use the mode itemnquerymap and that should return
just an image with the
selected features highlighted in yellow.
