It's standard practice, for a monolithic APP/EXE. Typically you can simply issue SET CLASSLIB TO < classlib >, that is, no IN clause required because VFP can find the lib in the APP/EXE. Just make sure to use ADDITIVE if you're using more than 1.

If you're using classes bound into .APPs different from the one that's currently executing, you might try SET PROCEDURE TO < TheAPP > ADDITIVE.
