ResumoCRYSTALLOGRAPHERS 307the points of intersection of the plane normals with the sphere of projection (Kleber, 1985). Software environment:The source code is written in Turbo Pascal 7.0.The distribution package includes an executable version for both the real and the protected DOS mode.No other libraries are necessary.The program offers a user-friendly graphical user interface (GUI) that is fully mousecontrolled except for the data input. Hardware environment:The program runs on IBM-compatible PCs under MSDOS 6.0 and higher.The unpacked distribution takes about 400 kbytes of disk space.The program uses VGA graphics and an IBM-compatible mouse.Output is in the form of PostScript files, which then can be sent to a PostScript printer or viewed with public domain software such as GHOSTSCRIPT. Program specification: STEREO-GRAMS is interactive and allows changeto a new orientation either by manual input or by a click on the Wulff net.All (hkl) can be indexed on screen.Angles between any two (hkl) can be calculated and rotations by ~ and p in the Wulff net are possible.It is also possible to select the hemisphere of the sphere of projection to be displayed.(upper/lower or both).The output PostScript file displays a 20 cm Wulff net with the fully indexed stereogram. Documentation:Since the usage is selfevident from the GUI, there is no need for an extensive manual.Instead, some online help is provided.Furthermore, the distribution includes an example Post-Script file and some input files.
