list := List clone

while (list count() < 6,
    n := Number random(1, 50) floor
    if( (list contains( n ) ) == Nil, //true if list doesn't contain n
        list add( n )
    )
)

Became:

l := List clone

while (l size < 6,
    n := Random value(1 50) floor round
    l appendIfAbsent( n )
)

l sort print
