Xailer & OZ Software

A few questions
1. If I want to create a dbf and index (cdx) from scratch with
fieldlist := { {KEYFLD1, "C", 10, 0}, {KEYFLD2, "D", 8, 0}, {FLD3,
"C", 20, 0 } }
indexes KEYFLD1 tag keyfld1, KEYFLD2 tag keyfld2
how this should be coded using OOP way in Xailer ?
2. If I want to use NTX rdd, how could I open several NTX files for a
dataset using OOP way in Xailer ?
3. What do I need to install in order to use ADS (local server), what
changes do I need to make for Q1 ?
Thanks.
