FIELDEVAL controls whether fields are updated automatically or on demand.
The Date field cannot be updated automatically regardless of the setting of
FIELDEVAL.
NOTE When the DEMANDLOAD system variable is set to 2, fields cannot be
updated until you use FIELD or UPDATEFIELD.
Contextual Fields in Blocks and Xrefs
Some fields are contextual; that is, their value is different depending on which
space or layout they reside in. For example, because each layout can have a
different page setup attached, the value displayed by the PlotOrientation field
can be different in different layouts in the same drawing.

For compatibility with previous releases, contextual fields in blocks and xrefs
are not updated when you insert them in a drawing; instead, the field displays
the last cached value. Therefore, if you want to use a contextual field within
a block, for example, a title block, you must insert the field as an attribute.
