A header file is full of compiler directives. The compiler compiles one file at a tiem. If you want ot use the header definitions in all your files you must include the header in all of them.

For prg's put #INCLUDE MyHeader.h as the first line, for forms, choose the form menu and then Include and type in the name and path to the header file. Classes are the same as forms.

In VFP 6 you can use the _include system variabvle to point to a header file and it will automatically be included for any NEW forms or classes you create (it will not affect anye xisting forms or classes).
