This chapter describes the use of the Graphical User Interface XLong. The interface XLong 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.

These functions are particularly useful for parameter intensive procedures such as the batch reduction.
Note XLong requires that the described MOTIF GUIs have been installed on your system. Also this chapter must be considered as an operating manual of the interface and assumes a general understanding of the Long context.
In this Section the following notations have been used:
