;Purpose:
;	Defines structures for data items shared between resident
;	runtime and userlibrary runtime.
;
;******************************************************************************

;-----------------------------------------------------------------------------
;	To minimize the number of global data items defined in
;	user library specific runtime and used in the resident
;	core runtime, they are defined in the following structure.
;	The user lib runtime will declare b$ULVars to be
;	of this structure type.  The resident runtime then only
;	needs to know the location of b$ULVars to reference
;	shared data items defined in the user lib.
;-----------------------------------------------------------------------------
