WinRAR SFX and running program after extraction

Hi guys,

I have the following SFX options file:

=====================================

;The comment below contains SFX script commands

Setup=myApp.exe

Silent=1

Overwrite=1

=====================================

What I want is for the RAR SFX to wait for myApp.exe to finish before terminating. At present, the SFX extracts the files, launches myApp.exe, and then exits.

Now I think it must be possible since in the help manual, its states:

If you have problems to use SFX to run InstallShield setup.exe, try to execute "setup.exe /SMS" instead of simple "setup.exe". This switch allows SFX to detect termination of the InstallShield setup program.

Now how does the SFX knows when a process has terminated?? What do I have to do in myApp.exe so that SFX will wait for it before terminating? (myApp.exe is a console application that I've written)

Thanks for any help or insights!
