if you want to wait until the program finishes:
system "notepad"
if you don't want:
system "start notepad"

see also Kernel#`

note that if you need to quote the program name, you have to add
another pair of quotes, because start
threats the first quoted string as window title.

system 'start "" "C:\Program Files\whaterver.exe"'
