It doesn't work on my system. What I get now is an endless list of "5"
printed out in the script console window (until I type quit to abort the
loop).

The multi-line version doesn't work in the script console window. Maybe
this is a difference between loading a script from a file and typing it
interactively. Until now I thought there was no such difference.
Q: What are the differences between executing a script from a file and
typing the same commands interactively?
If there really are any differences they should be pointed out in the
scripting documentation.

No, this is not the problem. It doesn't sit there only 5 seconds but
indefinitely until I type "quit".
Besides I wanted to test the dynamic echo that is bound to a variable.
(Therefore the "echo %{~cd};" command is in the initializing script
line.) And this dynamic echo works properly in the "while" loop, so why
shouldn't it work in the "for" loop?
