ShowNullsAs and NullValueText are properties in a Clarion LIST used for NULL column handling.
If the value in the column is null, then the contents of NullValueText is displayed (if column data type is a reference type, or if ShowNullsAs = NullValueText), or an alternate formatted default value (if column data type is a value type and ShowNullsAs = DefaultValue).
Additionally, there is a FormatValue event used to process column information.
