#### Description:

This attribute is a boolean value which controls how keys are used. If KeyCase is zero, then key strings supplied to any method are automatically converted to upper case before being used. If KeyCase is non-zero (the default), then supplied key strings are used without modification.

The value of this attribute can only be changed if the KeyMap is empty. Its value can be set conveniently when creating the KeyMap. An error will be reported if an attempt is made to change the attribute value when the KeyMap contains any entries.

Type:

  Integer (boolean).

#### Applicability

##### KeyMap

All KeyMaps have this attribute.

##### Table

The Table class over-rides this attribute by forcing it to zero. That is, keys within a Table are always case insensitive.
