Synopsis

&ATTYPE

Description

Allows you to read or set the data types of attributes. You can either assign a value (1-7) to &ATTYPE and put it where the 'data_type' parameter is used, or you can use one of the constants.

You can also specify a NULL attribute in case you haven't yet decided what data type to use. Later, you can go back and assign attributes to all objects previously specified as NULL.
