The "dos" unit is simply an implementation of Borland's Dos unit, ie. 
it has the same interface, but the implementation is completely 
OS-dependent. There's nothing bad about using it under Linux or Win32. 
It doesn't allow you to capture the output of a program though. popen() 
(in the Linux unit) does, but I don't know whether it allows you to get 
the exit code. Check the documentation (units.pdf).
