There's no builtin system() call because this is not part of the Pascal 
standard. But there is nothing to stop you from using your C-lib's system() 
call.

In C:        int system (const char *string);

In Pascal:   function system(s: cstring): integer; C;
             function system; external;

(I didn't try this, but have done simular things with fork() and others in 
the past)

Someday, we should get some units/modules to implement this ... oh, well, 
keep dreaming...
