DDLm dictionary version 4.1.0

_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 character set definition.
