# it forces the programmer to constantly repeat fairly common tasks every time a similar operation is needed

# it forces the programmer to program for the particular hardware and instruction set, like this [[assembly language]] pseudocode below:

<syntaxhighlight lang="asm">

MOV 1,EAX

MOV 2,EBX

MOV (ADD EAX,EBX), EAX

MOV 0,EBX

;; do it 5 times

MOV (ADD EAX,EBX),EBX

MOV (ADD EAX,EBX),EBX

MOV (ADD EAX,EBX),EBX

MOV (ADD EAX,EBX),EBX

MOV (ADD EAX,EBX),EBX

;; In fact, assigning is harder to do than this.

ASSIGN EBX,a
