This chapter describes the use of the Graphical User Interface XEchelle.
The interface XEchelle generates and sends MIDAS commands
to the monitor. Therefore, all operations performed with the interface
can also be performed manually by typing the commands on-line or
writing a procedure. The interface is however a convenient additional
layer of the software providing on-line help, visibility over
the parameter values and avoiding syntax problems.
These functions are particularly useful for parameter intensive
procedures such as batch reduction.

<B>Note</DIV>
<I>Using XEchelle requires that the described MOTIF GUIs have
been installed on your system. Also this chapter must be considered
as an operating manual of the graphical interface and assumes a general
understanding of the Echelle context.</I></B></BLOCKQUOTE>
