**** DOSPLUS ****
Written by: R.W. Kober
P.O. Box 181

DOSPLUS adds several features to the
C-64 WEDGE and DOS 5.1 that comes on
the TEST/DEMO disk. Here is a brief
description of what these added
features do, and why:
1. Entering @U or >U, followed by a
RETURN, will UN-NEW a BASIC program.
This will work even after a SYS 64738
has been entered.
2. Entering @* or >*, followed by a
RETURN will RESET the disk drive. This
will be verified by printing the disks
version of ROM to the screen.
3. With DOSPLUS resident in memory,
HEX or BINARY numbers may be entered
and will be accepted. Hex numbers are
preceeded with a '$', and BINARY with
a '%'. For example, if one enters
PRINT $C000, the computer responds
with 49152. Likewise, if one enters
PRINT %1111, the computer responds
with 15. HEX and BINARY numbers will
also work in a RUNning program. Both
of these lines will change the border
color to light blue:
10 POKE 53280,14
10 POKE $D020,%1110
I wrote this addition as I began to
program in ML in earnest, and was
constantly needing to convert from HEX
to decimal. I would look up a specific
location from within a monitor, and
then try to change it from BASIC with
a POKE statement. Converting easily
from HEX to decimal was necessary.
This version of DOSPLUS resides in RAM
from 52000 ($CB20) to 53247 ($CFFF),
and uses 1248 Bytes of memory. All of
the original commands and features of
the DOS 5.1 as contained on the
TEST/DEMO disk are retained intact.
Since DOSPLUS is ML, it is either
LOADed using ,8,1 or with a Basic
LOADer such as the one on this disk
called DOSPLUS LOADER.
To create your own DOSPLUS (if you
can't copy machine-language files) I
have included DOSPLUS CREATOR. By
LOADing and RUNning DOSPLUS CREATOR,
you can convert your own DOS 5.1 into
DOSPLUS.
