LEXICON READ OF DD(D0,0,'IX')    ICR (5038)

DD(D0,0,'IX') - Where D0 is the number of a Lexicon
file, and the 'IX' subscript contains a listing of Lexicon fields that are
cross-referenced.

Lexicon needs to be able to obtain the field number
that contains a classic Fileman cross-reference by
a direct global read of the Lexicon's Data Dictionary
(DD) 0 node, 'IX' subscripts.

^DD(<file>,0,'IX',<file/sub-file>,<field>)

The Lexicon has become so large that conventional
Re-indexing by Kill/Set logic needs to be replaced
with Index Repair logic, avoiding the killing of a
cross-reference and allowing users to stay on the
system without loss of access to the Lexicon package.
