filenames and the kernel

[Dr. T. Andrews]

From: jfh at rpp386.cactus.org (John F. Haugh II)
) Early MS-DOS and CP/M didn't include directories.
Both CP/M and early MS-DOS not only included directories, but they
also included several syscalls to deal with them (on top of which you
might build opendir() and friends).  Note functions 0x11 and 0x12 to
scan the directory.

One directory per disk.  To change current directory, use syscall 0x0E.
To get current directory, use 0x19.
