What's happening here?
name "calc-sum"
org 100h ;tells the program where to run the com file from on memory
mov cx, 5;creates register 'cx'
mov al,0 ;creates register al, stores the sum
mov bx,0 ;
next: add al, vector[bx]
inc bx
loop next
mov m, al
ret
;variables:
vector db 5,4,5,2,1
m db 0
I'm trying to comment the code but just failing really, commented the first three lines but i'm stuggling to do the rest. I'm crap with the low level stuff like this. Been an age since it was covered in class too, and notes have gone missing etc.

um well inc must be increment as in, increment (vector) bx. Loop next does it again but not sure how much of the code it does again. No idea on anything else. I did some 68000 machine code at uni but that was like (omg) 10 years ago (!)
Do they really teach this stuff these days? Surely its of no use unless you wanted to work in a very specific job supporting it? Would have thought it was all .Net and java now?

i *think* your post got screwed up and a load of random numbers and letters appeared.
