Hi all,
thanks for your comments. I have in the meantime tested many other
paramaters. It came out that I have used in the FIRST VERSION that
produced the error 'SCR_YSIZE=50'. This does not work in the way I want.
Setting 'YSize>1' (e.g. ysize=5) I get the behavior I want and expected
to get also for 'scr_ysize=50' ....
Thanks again, Good luck Frank
