The while language

It can be done with a single while loop, but it is not that clear:

while d == 0 do
  d := 1;
  a := 1
od
x := a / d;

Explanation, if d = 0, then d will be 1, also a will be 1. This ends the loop.

Now x is set to a / d which is fine, because if d was 0, a / d evaluates to 1.

Here's my code:

continue := True
while d = 0 and continue do
    x := 1
    continue := False
od
while d != 0 and continue do
    x := a/d
    continue := False
od

Would this work?

td := d
x := 1

while td != 0 do
    x := a / d
    td := 0
od
