Currently I'm maintaining a VFP8 manufacturing application which compiles completely into a single executable. As the project has grown and is in a constant state of development, I'm wanting to break up the system into several modules to allow for easier updating during the work day. For example, if I'm trying to implement a new bill of materials report for our Manufacturing Dept, I'd rather not have to tell the Shipping Dept to exit the program so I can replace the EXE with the newest version.

Fortunately, program is already divided cleanly by departmental function (Manufacturing, Shipping, Purchasing, etc.) and each module is already called from a master menu form. Can I "sub-compile" individual modules and run them with a DO command? If I run a DO EXE command, will global variables, etc., still pass through to the called EXE? If the user exits the called EXE will control return to the calling program?

Obviously I've never done this and ANY recommendations would be appreciated.

Thanks in advance.
