+USAGE
+dss field
+.ih
+PARAMETERS
+.ls field
+Name of target field to display.  If the null string then the \fIra\fR, 
+\fIdec\fR and \fIsize\fR parameters determine the image to display.  If
+specified as an image name, the WCS footprint of the image is used to
+determine the displayed image.
+.le
+.ls ra = 0.0
+RA (J2000) of field.
+.le
+.ls dec = 0.0
+Dec (J2000) of field.
+.le
+.ls size = 0.25
+Size of field (decimal degrees).
+.le
+.ls frame = 1
+Image display frame.
+.le
+.ls use_display = yes
+Display the retrieved image?  If 'no', the image is retrieved to the 
+system cache but is not displayed.
+.le
+.ls grid = no
+Overlay a coordinate grid on the image display?
+.le
+.ls verbose = yes
+Print actions?
+.le
+.ls save = yes

+DESCRIPTION
+The \fIDSS\fR task is used to query and optionally display an image of 
+the named \fIfield\fR.  If the \fIfield\fR param is the null string, 
+the \fIra\fR, \fIdec\fR and \fIsize\fR parameters determine the image
+to display.  If \fIfield\fR is specified as an image name, the WCS 
+footprint of the image is used to determine the query parameters.
+
+The \fIuse_display\fR parameter determines whether an image is displayed
+to the specified \fIframe\fR.  If disabled, the image will be retrieved
+to the system cache and the filename will be written to the \fIimname\fR
+parameter.
+
+.ih
+EXAMPLES

+2. Display the DSS version of the dev$ypix field, overlay a grid.
+
+.nf
