  Your loop as shown evaluates <condition>, and increments and tests
i and branches, up to 10 times, but assigns "ivar := i;" just once,
so setting ivar is a small part of the total time.

  If the loop typically has very few iterations, and performance is
a big problem, then you probably ought to unroll the loop anyway.

  Which of course is an extra increment operation, probably not a
lot cheaper than "ivar := i;".

  You could also make your own loop with your own, lasting, control
variable and your own "exit when i > 10;" to more exactly simulate
the Fortran.
