This is an oddball way of doing it, but...

If you rename the PBPW.exe file to something else.
And copy another program like Notepad.exe, and rename it PBPW.exe ...

Then when you compile, notepad will pop-up.
It's just there to stop the compile process, but leave it open.

Go to the folder with the file you are compiling, and you'll see a run.bat and run.pif.

Those contain all the parameters passed by MCS.

When you close Notepad, those files will be deleted.

Don't forget to restore PBPW.
