Part from Alex documentation. This one is very old (1996), although I think there is nothing special new added in later revisions.

[MRO3]

I didnt know if its part from any document. but for people like me its useful only if i want to know about certain subject instead of searching in several documents...
anyhow tnx for mentioning

[Ummi]

everybody have own needs, keep spirit to share !

[Cletus M.Kpartor]

Can u pls put this document back so that i can download it.

[MRO3]

its there why u cant dl it?
