execute SSIS package with config file from another dtsx file

Question

Basically I have a DTSX file that, after it finishes executing a few tasks, it reaches an "Execute Package Task" (Or "execute process task if you say so" which calls another DTSX file in the same project. I need to pass in with its call 2 arguments which will define variable values in the DTSX file being called, based on a computation of a previous task. How can i specifiy this in the tool? basically, the command line looks like this. how do I make it a package task

"E:\\LOCATION_OF_DTSX_FILE ARGUMENT1 ARGUMENT2" OR through a bath file "LOCATION_OF_BAT_FILE.bat ARGUMENT1 ARGUMENT2"

Thanks a bunch

If you are calling a package from another package, use a parent / child configuration. Essentially, the parent and child packages have variables that are the same name. The child package has a parent config (not a config file). You configure the variables in the execute package task.

Alternatively, you can call dtexec with the /set switch which will allow you to set any value in the package that you are calling. This method is much more cryptic though, I would suggest the former.
