:-D You are right.
My problem thought is that my As400 administrator does not want to give
me any other access, as she is "afraid" I might screw things up... funny
isn't it?
Screen scraping is my only way of automating some work for now, so I
must stick with it, even if I would really like a better programmatic
interface.

Yup.

Ok, I get it.
Fortunately there are not many screens I have to deal with, so I will
put in checks to the screen before and after each insertion of set of
values, and just before each enter. It's suck, I know, but it should work.

Sigh :-(
