     The aim of this set of programs is as follows. Imagine 
that we have found in literature the crystallographic 
structure of some substance, and we want to perform some 
calculations for this structure, so we need machine 
representation of the presented data. The presented programs 
allow one, with the use of the parameters of the lattice and 
coordinates of atoms, to build and preview the structure. The 
program produces file *.MOL (OUP Molecular Modelling Package, 
1988). Auxiliary programs allow one to convert *.MOL into 
*.X_R (plane table of coordinates of atoms), *.ZMT (MOPAC, 
HyperChem), and *.HIN (HyperChem), as well as to prewiev 
them. The program RAH_XYZ converts *.ZMT from the 
representation based on internal coordinates to that based on 
Cartesian coordinates.
     Caution: in old files of description of structures 
(*.INC), sometimes it is necessary to replace the calls of some 
subroutines in old format by those in new format; this should not
produce difficulties.
