DDLm dictionary version 3.14.0

_type.indices

Name:
_type.indices

Definition:

   
     Used to specify the syntax construction of indices of the entries in the
     defined object when the defined object has 'Table' as its
     _type.container attribute. Values are a subset of the codes and
     constructions defined for attribute _type.contents, accounting
     for the fact that syntactically, indices are always case-sensitive
     quoted strings.

     Meaningful only when the defined item has _type.container 'Table'.

     See the definition for _type.contents for the characterset definition.
