But inside the routine with "out" parameter I had expected to get the same
warning ;-). But this was before I learnt that at least something of an "out"
parameter reaches the routine.
Why is this 'passing a potentially uninitialized variable to a "var" parameter'
('bla does not seem to be initialized') message a warning for arrays and a hint
for basic types?

I don't understand this restriction. In the code High() works for open arrays
at run time.
