Hm... i4gl:

define x integer,
      ar array[7] of integer
main
  for x=0 to 7
    let ar[x]=100+x
    display ar[x]
  end for
end main

->

       100
       101
       102
       103
       104
       105
       106
       107

(In a fact, it displays everything ok in case when x is to 100 too
:-))) but that is another problem)

Aubit compiles the code, but asserts array out of its bounds when run.
It is just incompability, not aubit bug, of course. (I use arrays with
weekday() often, so I run into problems very quickly :-)

What should I set, if I want multiple prompts (without clearing screen
during this input phase) and then I need "display at" work in 4gl?
Should it work with CONSOLE?

It did not help :-(
