Mmm. Well I kind of think I know what I have to do, it's break the VAR WORD Total up into two BYTES, allocate them each a memory space B1 & B1+1 (from the prog below) WRITE the BYTES to the memory locations then READ them back.

Code:
        INCLUDE "modedefs.bas"          ' Include serial modes

SO      VAR		PORTC.6					' Define serial output pin

B1      VAR     BYTE					' Address variable
W2      VAR     WORD					' Data variable


mainloop:   

		For B1 = 0 To 12 step 2			' Step 2 because each word requires 2 bytes of memory
        	W2 = B1 + 1000          	' Add 1000 to address
        	Write B1, W2.HIGHBYTE		' Write high byte of word
        	Write B1+1, W2.LOWBYTE		' Write low byte of word to next address
		Next B1

		For B1 = 0 To 12 step 2			' Step 2 to get word size data
        	Read B1, W2.HIGHBYTE		' Read high byte
        	Read B1+1, W2.LOWBYTE		' Read low byte
        	SerOut SO,T2400,[#W2," ",10,13]	' Display the word data
		Next B1
		
        SerOut SO,T2400,[10,13,10,13] 	' Skip 2 Lines

        GoTo mainloop                       ' Forever
My reading of the program above is that B1 = 's ( 0,2,4,6,8,10,12) + 1000 this is then written and read from memory location B1 & B1+1 into WORD W2 am I close?
