etc etc.

There is a further significant difference between the Pascal
repeat..until and the 'C' do..while. In Pascal, 'repeat..until'
delimits a statement-list, not a single statement as in 'C'.

Otherwise you would have to begin a multi-statement 'repeat..until'
with 'repeat begin', and end it with 'end until'. There is no formal
need for such redundancy.
