DIRECTORY outputs a list of file names on the disk in the currently selected disk drive.
If DIRECTORY is used with an input, it outputs the file names specified by its input. A drive specifier may be used to access a disk drive which is not currently selected. A ? may be used to match a single character except period and a * may be used to match a group of characters not including a period.
