Thanks a lot for the reply, I've tried it and it stays the same :\ just 
spits out the characters, and no colours.
I've tried it with ksh (the original, not the public domain) and it is 
working as expected. So it seems to me that pdksh is broken; or not... 
I don't know. I thought that pdksh wants to "clone" ksh88 and ksh93. 
This rewrite indeed implements some features from ksh88 and some from 
ksh93, but surely not all, and some of them are broken. The 
maintainer's latest version dates back to '99 and I just saw the 
existing bugs' page... I could've passed over this colour trouble, but 
the alias exporting is not working which I surely need.
As I don't want to use the original ksh (although it is working :) I 
guess I'm just stuck with the good old bash, and use pdksh on my bsds.

Thanks for your efforts, and help.

Daniel
