How about building COM components instead of separate APP if you want your system broken in small pieces?

>I am putting together a system were the menu in proj1.app (which has the READ EVENT) calls proj2.app. In proj2.app a menu is invoked that has DO FORM statements for forms contained in proj2.app. The problem is that the specified form is not found since is not in proj1.app where the READ EVENT was invoked. I find it advantageous having the system broken down small projects. What is the proper method of handling this?
