ZCOUT has two main functions;

1. To emulate, on screen, the Pascal 1.1
   screen firmware protocol.

2. To apply various patches that make
   GBBS.PRO easier to use, and more
   asthetically pleasing.

 These functions are both implemented
without any permanent modifications to
the main GBBS.PRO program code, thus
allowing your own patches to be made!

 When you run the ZCOUT install routine,
extra code is added on to the end of the
ACOS system boot file. When ACOS boots,
it calls this code, which loads the main
ZCOUT program code into auxilliary
memory via the ProDOS volume /RAM.
 The ZCOUT hook routines are saved in
ACOS.OBJ by the install routine, on top
of the current console driver code that 
you have selected via GBBS CONFIG.SYSTEM
 All patches to ACOS are then made by
ZCOUT whilst ACOS.OBJ is in memory, and
hence are not made permanent!

 During Pascal 1.1 firmware emulation,
carriage return ('CR' $0D) is the only
non standard, as it also generates a
line feed ('LF' $0A) to be compatible
with the way GBBS.PRO was written.
 This feature can be disabled by POKEing
the value 0 into location $92B (2347),
and re-enabled by POKEing it with the
value 255 ($FF).

 When ZCOUT is initialised, it defaults
to having the cursor turned on, which
conforms to the Pascal 1.1 standards.
 This allows the sysop to see exactly
what is on the user's terminal, cursor
and all.
 When GBBS.PRO goes to read input from
the modem and keyboard, it doesn't
conform to it's own standards of console
handling, and instead displays the
underscore character and backspaces on
top of it before testing for input.

 Considering ZCOUT's default of having
the cursor on, this results in the input
cursor being a pipe character (inverted 
underscore). ZCOUT makes a soft patch to
GBBS.PRO to make it use standard entry
points, and thus supply the correct
cursor. Another way to turn the cursor
off without sending a CURSOFF character,
is to change location $92C (2348) to a
value of 255 ($FF) before a TEXT : HOME.
 This initialises ZCOUT with the cursor 
routines disabled.

 The input cursor can be changed from an
underscore by changing location $92A
(2346) to the ASCII value of the new
character before an input.

 The COPY command strips out line feeds 
from files, so ZCOUT makes a soft patch 
to correct this on initialisation.

 To remove this patch, change location
$92D (2349) to the value 255 and do a
TEXT : HOME.

Restrictions:

On ACOS bootup, /RAM must be formatted
and empty. This is done by ProDOS when
it boots, so as long as you save nothing
to it, everything is ok. Once ACOS is up
and running, you may use /RAM as long as
you do not touch the file ZCOUT.IMAGE.

The ZCOUT program code requires at least
a 65C02 cpu to run, and a message will
be displayed on bootup if it is not.

Various other GBBS.PRO bug fixes are
included in ZCOUT, such as the ^O CV/CH
save problem. Greg was calling a common
routine to save CV/CH when ^O was used
to turn PRG: off. This routine also had
other functions, which Greg never knew
about because of other bugs which fixed
this one up.
 
  Any questions on GBBS.PRO patches can
mailed to the address below. Include
either a SAE or your phone number, and
any moneys you can spare to keep me
interested in updating ZCOUT.

This program is FREEWARE, but donations 
are gladly accepted.
