Author:   Bill Ross
Date:     4/16/98

Programs: xleap

Severity: convenience

Description:	Program exits if 'Add H and build" is used when atom types
		with unknown hybridization are present (e.g. some monoatomic 
		ions).

Workaround:	Define the hybridization for all atom types in leaprc
		using addAtomTypes.

Fix:		Add the indicated line to model.c:
-------------------------------------------------------------------------
*** OLD model.c
--- NEW model.c
***************
*** 1168,1173
  		/* Take account the hybridization state */
  
  	switch ( iAtomHybridization(aAtom) ) {
  	    case HSP3:
  		iNeeded -= 0;
  		break;

--- 1168,1178 -----
  		/* Take account the hybridization state */
  
  	switch ( iAtomHybridization(aAtom) ) {
+ 	    case 0:	/* monoatomic ions and ...? */
+ 		VP0(( "(%s: hybridization for type %s unknown)\n",
+ 					sContainerName(aAtom), 
+ 					sAtomType( aAtom ) ));
+ 		break;
  	    case HSP3:
  		iNeeded -= 0;
  		break;
