On plain DOS, you can use

	system("prog /option file1 file2");
or
	`prog /option file1 file2`;

which both do file globbing (converting "*.txt" to a list of files), or

	system('prog','/option','file1','file2');

which doesn't do file globbing: "*.txt" would simply literally be passed
to the program.

system() and backticks behave differently with regards to STDOUT and
STDERR. I think system() reuses STDOUT and STDERR of the script (except
tied handles, that doesn't work), while backticks capture the program's
STDOUT into the value returned; STDERR still goes to the script's
STDERR.
