Bonnie,
You're really close already. CLASS DEFINitions work just like procedures. If you want to lump them all together in one file, other than your MAIN program, just make sure to SET PROCEDURE TO xxxxxxx in your main program. After that, you're golden!

PS. I use ALOT of program based DEFINES in my projects. If you want to pull them all into a VCX (so you can diagram them with the Visual Modeling Wizards) you can use TRUE, a set of utilities by Tom Rettig.

HTH,
Marty
