I’ve got to write a program in IAS Machine assembly language that sums every item of an array, except the array[i] item.

Although, i’ve not yet found a way to test equality of two values to determine whether the item of the array is the one i won’t sum in the iteration, as i can’t just subtract one from another, as the only conditional operator tests for values >= 0, having no way of knowing if it’s just zero.

I’ve created two variables, one to point to the item i will not sum in the iteration, and one ‘j’ variable.

021 00 00 00 00 05 # variable j 022 00 00 00 00 01 # constant 1 024 00 00 00 00 30 # pointer array[i]

My plan was to compare the variable j with the position of array[i] to see if they are the same, then not adding it to the sum.
