Hello Ladies and Gents...

..... I got it figured out

PROBLEM : By default AE does not provide the ability to select Progress Data Types when Adding Parameters to Class Operations.
SOLUTION: ..... Read following instructions.
STEP ONE (Define the Progress Code Datatype )
1.1 : Select "Settings" on EA toolbar
1.2 : Select "Code Datatypes..." on the Settings drop down menu
1.3 : You are now in the window titled "Programming Language Datatypes"
1.4 : Click the "Add Product" button and add the Product name "Progress"
1.5 In the "DataType" fill-in widget type the data types i.e. memptr etc ... see list below.
1.6 Save each DataTye to create list
STEP TWO ( Assign Language to Class)
2.1 : Right click on Class
2.2 : Left click on "Properties..." in the class's drop down menu
2.3 : Choose "Progress" in the "Language" drop-down box.
( note if not in list then you need to review the above instructions in "Step One" 1.1-1.6 .
