+**  PRINT RELATION
+**
+**	Parmv[0] through Parmv [parmc -1] contain names
+**	of relations to be printed on the standard output.
+**	Note that this calls AApratt, so all the output formatting
+**	features associated with AApratt are available here.
+**
+**	Parmv[parmc] is -1 for a "normal" print, -2 for headers on
+**	every page, and -3 for all headers and footers suppressed.
+**	err_array is set to 0 for a good relation, 1 for no
+**	relation by that name, and -1 for a view.
+**
+**	Returns:
+**		0 if no errors else the last error number
