683.0. "Any sample using multiple ranges of Key?" by DEKVC::DONGWONSHIN () Mon Mar 17 1997 12:29

Hello,
 
Does anyone have sample programs using multiple ranges of key at the single 
application ?

And is there any difference in the meaning of between multiple ranges of key 
and the number of key segment ?  

Thanks a lot.
