Session parameters are listed by the command <TT>SHOW/ECHELLE</TT>. It is recommended to use this command to control the actual status before executing any further reduction step. Current parameters are saved with the command <TT>SAVE/ECHELLE name</TT>, where <TT>name</TT> is the session name. This command will be used whenever you want to interrupt a session which then can be restarted at any other time. Current parameter values are set to the default value with the command <TT>INIT/ECHELLE</TT>, or set to the values of a previously saved session with <TT>INIT/ECHELLE name</TT>. <P> Relevant session parameters can be defined for each command in the usual way: <BLOCKQUOTE> <TT>command/qualifier parameters</TT></BLOCKQUOTE>or can be defined in explicit form as<BLOCKQUOTE> <TT>SET/ECHELLE param=value [param=value ...]</TT></BLOCKQUOTE>where <TT>param</TT> is the parameter name and <TT>value</TT> is the assigned value. The assigned values will be maintained until you save them for later reference. Current parameter values are re-assigned either by <TT>INIT/ECHELLE</TT> or by another <TT>SET/ECHELLE</TT> command. <P> Please note that the session concept is part of the high level command structure (level 1 and above). If level 0 commands are used one has to specify explicitely ALL the parameters required by the level 0 commands, despite the fact that some of them may already have been set via <TT>SET/ECHELLE</TT>. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html3548" HREF="node171.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html3545" HREF="node169.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html3539" HREF="node169.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html3547" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <BR> <B> Next:</B> <A NAME="tex2html3549" HREF="node171.html">Image Formats</A> <B> Up:</B> <A NAME="tex2html3546" HREF="node169.html">Implementation</A> <B> Previous:</B> <A NAME="tex2html3540" HREF="node169.html">Implementation</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
