EXYZ Instruction
EXYZ atomnames
The same x, y and z parameters are used for all the named atoms. This is
useful when atoms of different elements share the same site, e.g. in minerals
(in which case EADP will probably be used as well). The coordinates (and
possibly free variable references) are taken from the named atom which
precedes the others in the atom list, and the actual values, free variable
references etc. given for the x, y and z of the other atoms are ignored.
An atom should not appear in more than one EXYZ instruction.
