	! Author : Neil Rieck
	! Created: 94.02.28
	! History:
	! ver who when   what
	! --- --- ------ ---------------------------------------------------------------------------------------------------------
	! 100 NSR 940228 1. original work
	!     NSR 940314 2. added EDIT$ to parameters
	!     NSR 940315 3. removed EDIT$ from parameters and now pass double quotes with xtra space
	!     NSR 940420 4. changed the map size from 40 to 15
	!     NSR 000502 5. added trace code to find a potential OpenVMS 7.2 problem					bf_trace
	!		 6. changed mapped string lengths from 255 to 80
	!		    (this will reduce the run-time memory requirements of this function by 2100 bytes)
	!     NSR 040528 7. changed mapped string lengths from 80 to 132 (we're on Alpha now so this is no big deal)
	!     NSR 061117 8. changed trace file directory from csmis$msg: to csmis$dat:
	!     NSR 070709 9. changed mapped string lengths from 132 to 255 (the 132-character limit was tuncating the
	!			mailing address list in EXPRESSVU PUBLIC VIEWING)
