Argument	Type	Description
attr-list	N	specifies the identifier of an SCL list that contains the attributes for the computed column

Details

Only the NAME item is required, but any column attributes accepted by the _setColumnAttributes method can be passed in this list. If no type is specified, numeric is the default.

Data values for the computed column can be assigned or queried using SCL code. The computed column is added at the end of the row in the data vector. The viewer, if any, determines if the column should be displayed and how to display it.

Note: The _addComputedColumn method cannot be called from the model's SCL entry. [cautionend]
