This is an implementation-specific issue; there's no way to do
it portably because the details depend on things like which
operating system you're using, therefore there's no way to
build it into the language.  It has to be done via library
modules.

What you need to do is read the library documentation for
whichever compiler you're using.  Some compilers come with
an easy-to-use library procedure to do the job, and some don't.

A general comment to all beginners (though I doubt that it'll
do any good): if you want to ask questions like this, then you
need to specify which compiler you're using, which operating
system, etc.  If the question is too vague then you're unlikely
to get a useful answer.

With TopSpeed 1.17 you write:

	Storage.ALLOCATE( address, MAX( CARDINAL));
        error_code := Lib.Execute( program, command_line, address,12000);
	IF error_code # 0 THEN
		... (* error, DOS error code = error_code *)
	END
	Storage.DEALLOCATE( address, MAX( CARDINAL));

Thats all.
