	! notes  :	note: for this peek trick to work, we must...
        !               1. declare LONG BY VALUE passing mechanism in the calling program (we are using 32-bit
	!			addresses in this 64-bit computer) like so:
	!			external basic$quadword function wcsm_peek_quad( long by value )
        !               2. declare basic$quadword BY REF passing mechanism in actual function
        !
	! ver who when     what
	! --- --- -------- --------------------------------------------------------------------------------------------
	! 100 NSR 20110414 1. original work (a spare time effort)
	!==============================================================================================================
	function basic$quadword wcsm_peek_Quad(basic$quadword incomming by ref)	! quad function receives quad address
	option type=explicit							!
	%include "starlet"      %from %library "sys$library:basic$starlet"      ! system services (and basic$quadword)
	wcsm_peek_Quad = incomming						! exit with this value
	end function								!
