Part II
Given the following part of a PEP/8 program, write the assembly code necessary to sum the
(full-word integer) values in an array and write the result. (Each array value is two bytes.)
Output the sum after the loop to accumulate. No object code is necessary, just the assembly.
You can assume that the array has been defined by previous code. Also, assume that the entire
array is filled with significant data. Do not use impure code, that is, used indexing to write the
array values. Also, use a loop for your solution.
Hint–use the accumulator to hold the sum in the loop.
MAXSIZE:
intlist:
sum:
main:
br
main
.equate 10 ; size of array in 16 bit words
; decimal 10 default is decimal
.block 20
; array declaration
.block 2
; to hold sum of array values for output
; main program will sum all array values
; and output result
; there is no need for a loop control variable
