Remarks
This function allows you to set the value of a field using a symbol that specifies the field name. Within generic database service functions, this allows the setting of field values without the use of the macro operator, among other things.
By default, this function operates on the currently selected work area.
It can be made to operate on an unselected work area by specifying
it within an aliased expression
Shared mode:
For a shared database, this function requires a record lock.
