Hallo Martin,

hast Du Dich schon gut eingelebt?

I am not meaning that !D.Y_CH_Size don't work more I like to say it's not
exactly.
We found differences between aix and NT IDL.

If you try to get the height of one char or one line this will be quiet good
enough. But what's with
formulars or many lines with increments or exponents.

How did you determine the space between two lines?

Gruss

Reimar
