Arrays
The Progress database allows you to define fields as arrays, also called field extents. Progress interprets specially named data-source columns of the same data type as a Progress field with the same number of array elements. You must name the data-source columns column-name##1, column-name ##2, and so forth. In Informix, however, you must name these columns column-name__1, column-name __2, and so forth. (Informix does not allow the pound sign (hash sign) in object names.) The DataServer creates a single field definition in the schema holder for the field extents. See the "Adding Extended 4GL Support" section in "The DataServer Tutorial," for instructions on adding these columns automatically with the Progress-to-ODBC utility.
