Thanks, that does the trick!

However, since I'd much rather speak my native tongue! Is there a way to say
this  natively in "D"?

Phobos has no function to execute programs actually.
I'd like file.d to provide an execute() function beside read() and write().

Anyway, if you don't want to use the C standard library and you're running
Windows you can use CreateProcess instead, but using it is very awkward.

In C world this function would be in <process.h>, not <file.h>, but perhaps
execute() could alternatively take a file object instead of a pathname.

It's pretty important to have this;  depending on the OS command line syntax
makes you system dependant.
