				translate.c

Purpose:
	In default editing mode (no editing), translate atoms in macromol.
	complexes which are caught.  TranslateComplex_ function takes care
	for stereo data and for position_changedF.  If editing atoms (mode
	index equal to 1), translate only the selected atoms. If edit mode
	index is equal to 101,  resize the selected portion of one or more
	objects.

Input:
	(1) Pointer to MolComplexS structure, with macromol. complexes.
	(2) Number of macromolecular complexes.
	(3) Pointer to RuntimeS structure.
	(4) Pointer to ConfigS structure.
	(5) Translation shift.
	(6) Translation direction (axis) identifier (1 = x, 2 = y, 3 = z).

Output:
	(1) Atoms translated in all caught macromolecular complexes.

Return value:
	No return value.
