For that, system() works fine.
If you want the called program to start and return immediately 
to the main pgm, you call the other program(s) with an '&', as 
in system("exu foo &",0)

That starts "foo" running in the background. If foo is a 
graphics pgm, its window will pop up.

Without the '&', your main program will wait until the 
called pgm is finished.

However, if the called program prints text to the screen, then 
there's a problem: when a Eu program quits, it displays "Press Enter"
and waits. This stops further processing by the main program.
I don't know why this is necessary, but that's what Eu does.

You can also use shell commands such as wait, I've never needed 
to use those.
