Problem Statement

Start with a value at 0. Loop while value mod 6 is not equal to 0. Each time through the loop, add 1 to the value then print it. The loop must execute at least once.

Let's start with the solution:

code CrLf=9, IntOut=11;
int V;
[V:= 0;
repeat  V:= V+1;
        IntOut(0, V);  CrLf(0);
until   rem(V/6) = 0;
]
