A graphical user interface, using the Interactive Data Language (IDL) widget toolkit, for calculation of
spectral properties of synchrotron radiation sources and for interaction of x-rays with optical elements
has been developed. The interface runs presently on three different computer architectures under the
Unix operating system -- the Sun-OS, the HP-UX, and the DEC-Unix operating systems. The
point-and-click interface is used as a driver program for a variety of codes from different authors
written in different computer languages. The execution of codes for calculating synchrotron radiation
from undulators, wigglers, and bending magnets is summarized. The computation of optical
properties of materials and the x-ray diffraction profiles from crystals in different geometries are also
discussed. The interface largely simplifies the use of these codes and may be used without prior
knowledge of how to run a particular program.
