COVER is a utility to print a sorted directory listing in such a
format as to allow the listing to be cut and inserted into the sleeve
with the diskette. It was written by Dan Daetwyler of Arkansas and
first published (and placed in the public domain) in the January 1984
issue of "Dr. Dobb's Journal". Anyone interested in the details is
referred to that issue.

To run, insert diskette with the program in the default drive and
type COVER. The program will prompt you for the ID of the drive that
contains the diskette to be listed. Type the appropriate letter
(either case) ONLY -- no colon or RETURN. The program will then ask
for a title to appear on the listing. The title may be up to
forty-four characters; if you do not want a title, simple press ENTER.
This process continues until ESC is entered at the drive ID prompt. The
program prints two envelope covers per page; if exited via ESC, it will
advance the paper to Top-of-Form and restore the printer to its power
up defaults.

The program issues Epson printer control codes for selecting
compressed print, 1/8 inch line spacing, and 44 lines to the logical
'page'. Those with IBM/Epson printers should be able to use COVER as
is. Those with a printer that uses different control codes with have
to 'patch' the program (using DEBUG or some other such program). The
sequence to initialize the printer begins at location 13C; the Epson
sequence is six bytes long (1B 30 1B 43 2C 0F) but it is padded with
zeros so that there is room for eleven codes altogether. The string
MUST terminate with a zero for the DOS call to work correctly. The
printer restore sequence is two bytes long (1B 40) and begins at
location 148; again, it is padded with five extra zeros for patching
room. If this is insufficient for setting up your printer, you might
try zeroing these sequences out and setting up your printer outside the
COVER program.

NOTE: Cover issues ONLY the DOS call interupt. This should insure
that it can run on any MS-DOS machine not just the IBM compatibles.
It has been successfully run on a TI Professional Computer with no
modification whatsoever.
