<TITLE>Commands supporting SICS status displays</TITLE>

<BODY>
<H1>Commands For Supporting SICS Status Displays</H1>
<P>
The implementation of many status displays is greatly simplified by
letting the SICS server do some of the hard work. The operation of
these commands is usually invisible to users. Some even do not
generate output accessible to the user because they send uuencoded
information. This section documents these commands for completeness
and as a reference for status display client writers.
</P>
<h2>The Reflectometer AMOR</h2>
<p>
The reflectometer AMOR probably has the most extensive of such
modules. It does a lot of things. It is configured into SICS with the
MakeAmorStatus command. Let us assume that it is configured into the
system as amorstatus. This object supports the following commands:
<dl>
<dt>amorstatus interest
<dd>This registers this connection for receiving automatic
notifications. Automatic notifications send are:
<DL>
<dt>SCANSTART
<dd> At scan start a message <b>ScanClear</b> is sent followed by the
uuencoded new x-axis for the plot.
<dt>SCANPOINT
<dd>At each scan point the arrays of counts in both detector are sent
in uuencoded form labelled arrow_spinupup and arrow_spinuplo.
<DT>COUNTSTART
<DD>The start of counting on the histogram memory. Send a message
<b>TOFClear</b> and then the uuencoded time binning labelled
arrow_time.
<DT>FILELOADED
<DD>activated each time user defined model data is loaded into the
SICS server. This data gets send as arrow_name in uuencoded form. Both
x- and y-axis are sent in floating point.
</DL>
Please note that floating point data is transformed to fixed point by
multiplication of 65653 before transfer. The first number in each
uuencoded message is an integer describing the length of the data. In
case of double data such as fileloaded the y-data follows immediatetly
after the x-data. Also the approriate data is automatically sent after
the interest command.
<dt>amorstatus collapse
<dd>sums all counts in all detectors in time and sends the data back
as an uuencoded image. The first two numbers in the message define the
dimensions of the data.
<dt>amorstatus sample name x1 x2 y1 y2
<dd>Sums the detector counts on an area defined by the rectangle x1,
x2, y1, y2. The length of this is the time binning. The data is sent
back in uuencoded form labelled arrow_name.
<dt>amorstatus clear
<dd> Clears all user loaded data.
<dt>amorstatus load filename scale
<dd> loads user defined data for distribution to the status display
clients. The y data is scaled according to the scale factor provided.
