Explanation / Answer

; code as per ARM, first four parts only

left   DW   844; define a 16-bit variable and store 844 in it

right   DW   3150;

result   DW   ?; define an empty word for storing the sum

diff   DW   ?; this will store the difference

   MOV r0, left; move one value into register r0
  
   MOV A, right; move the other value to accumulator
  
   ADD A, r0; add the two values and store the result in accumulator
  
   MOV result, A; move the sum stored in accumulator to the defined variable result
  
   CMP left, right; compare the values left and right to find the greater number, to compute the positive difference

   JGE greaterLeft; if left is greater, jump to label greaterLeft
  
   MOV A, right; if the jump did not happen, implies right is greater than left, move right to accumulator
  
   SUB A, left; subtract left from right that was stored in A

   MOV diff, A; store the result in the variable

greaterL:
  
   MOV A, left; move the number in left to accumulator
  
   SUB A, right; subtract right from A
  
   MOV diff, A; store into the defined variable
  

message   DB   "Hello World!"; define a string

array   DW   1,2,4,8,16,32,64; defining a multi-byte datastructure
