I have an subprog.exe which is called from main.exe. These 2 exe files are developed by 2 different people. I've placed these exe files in our NT server. Users calls the main.exe via a shortcut icon (to main.exe in NT server) on their desktop. I use VFP tables which are placed in the same NT server.

Is this the correct way to setup the system? Is there other more preferable options? I would like to avoid having to copy main.exe & subprog.exe to every user's computer to avoid having to recopy again whenever there are changes to main.exe & subprog.exe.

Since subprog.exe is called from main.exe, how do I ensure that the variables & pointers & all other setups from main.exe cannot be accidently modified in subprog.exe? I've looked up PRIVATE, but not sure how that works.

I like to make sure as exiting subprog.exe, all mem. variables / buffers /pointers / cursors /tables /etc. are released before control goes back to the calling program, main.exe. How do I do that without disturbing the variables / tables / pointers, etc. of the main.exe?

What settings should I set up to optimize the application? SET ESCAPE ON, SET OPTIMIZE ON , ...... ????

Thank you all!
