Here is an example 16 bit adder program for the DAVIAC-1:

- 
-\	RAM Variables
-	ORG		0800H			\RAM at 0800h
-	DEF		X_Lo		*1
-	DEF		X_Hi		*1

-	DEF		Z_Lo		*1
-	DEF		Z_Hi		*1
-	DEF		Carry_Lo	*1
-	DEF		Carry_Hi	*1
-	ORG		0400h
-\
-\	load some numbers
-\
-\	Put numbers in X and Y at 0800H by hand from Control Panel.
-\
-\
-\	16bit ADD  X + Y -> Z + Carry_Hi
-\

-\
-	NOP
