Sometimes I was wondering why we need to use the 'ds' directive :
-----------
dseg at 30h
stack: ds 16

;this reserve 16 bytes for the stack at address 30h.
;;Anyway, what do you mean by 'reserve'. Since without the 'reserve', ;;we can also use that portion of data space without problem??

cseg
mov sp, #stack-1
-----------------

thanks.

p/s isn't the above code work well as
mov sp, #29h. Then why we need to use the 'ds' directive ?
