Your manager has to write the actual batch file. Let's say your manager is called "manager.exe", you start it with "go.bat" and the program to run is "run.bat". go.bat: @echo off ::start the file manager manager :loop ::if the manager didn't create a file, it exited if not exist run.bat goto eof call run.bat del run.bat ::run the manager again, but let it know it's returning from a program manager -restart goto loop :eof run.bat: ::whatever program was selected by the manager @notepad ::one problem with this technique is having to take care of arguments ::in particular, you have to double up percent signs -- Jason.
