TYPICAL OBJECTS OF TYPE Null Object

NullObj

</defs>

This type represents a null object.

Normally if the cell containing the Value of a Key-Value pair is blank, the Value is regarded as a null object.
There are though circumstances when a null object needs to be explicitly constructed because a blank cell can either not be used or is interpreted differently.
The function here can be used to generate the required null object.
