[aplusdev] Primitive function Deal?

[Alexander Skomorokhov]

Stevan,

I just did one more experiment. I copied on a floppy:
17.06.2001  21:23                5.120 k.exe
17.06.2001  21:28              175.104 k20.dll
07.09.2001  04:04                3.038 olap.k           /* you script

(totally only 183K!). Put this floppy to a machine (W2000), which never
heard about K, change to a: and typed in DOS prompt

k olap.k

And it works! Terrific.

I see. Sounds reasonable.

Yes, that's important issue.

I probably try to do this. Are you ready to answer some questions
if they arise?

The first one is (probably stupid one) meaning of:
"data in the form of a hierarchical star scheme, denormalized".
Could you please explain this in brief?

If it works in "ASCII-mode", then fancy GUI is not a problem at all:-)

Interesting remark. Well,  incrementing an integer doesn't look like a good
benchmark any way.
