Mike,

The short answer is no. The longer answer is this.

An include file is a set of compiler directives. They are processed when the compiler compiles the source code into pcode. Each class is compiled separately, therefore each class must have its own include file declaration. The include file for the superclass will be used to compile the superclass but it is not used to compile the subclass.

Your _INCLUDE setting will automatically set the include file for classes and forms created after the variable has been set. The include file will not be added to any existing classes or forms. You need to use the Menu's Include file functionality to set an include file for the existing things.

Any new forms or classes you create will use the _include setting to set the include file for those new things.
