    This document explains how to use the byte mode floppy handlers with
the OS/78 and OS/8 operating systems. It also explains how the  handlers
are used to transfer files from OS/8 or OS/78 to COS/310.

INSTALLATION
____________
OS/8
____

    The OS/8 BUILD program is used to install the byte mode handlers  in
the OS/8 system. This  requires  the  file  "RXBNS.BN"  to  install  the
non-system handler, and the file "RXBSY.BN" to  install  the  non-system
handler. The file "RXFIX.SV" must also be present on the system device.

    To build a system floppy, boot a normal OS/8  system  floppy  in  RX
drive one. Place a blank floppy in drive zero.

    Start by running the OS/8 BUILD program.

.SET SYS NO INIT                this insures that the system will not
                                automatically  start  a  program   after
                                being built.
.RUN SYS BUILD                  Run the builder.
$PRINT                          Print the handler tables
RXSY:   *SYS
RX02:   *RXA0   *RXA1
KL8E:   *TTY
$LOAD RXBSY                     Load the two handlers
$LOAD RXBNS
$PRINT                          Check the load.
RXSY:   *SYS
RX02:   *RXA0   *RXA1
KL8E:   *TTY
RX8:     RXB0    RXB1
BYTE:    SYS     RXB0    RXB1

    Then, to install the non-system handler:
$INSERT RX8,RXB0-1
    If you want to create a byte-mode system:
$DELETE SYS
$INSERT BYTE,SYS,RXB0-1
    Don't insert the RXB0 or RXB1 from the RX8 set if you want to create
a byte-mode system. Use the co-resident files that are part of the  BYTE
handler.

    Now, finish the re-build.
$BOOT

    If you did not try to build a system device, the response will be:
SYS BUILT
.
    If you built the system, the program will ask:
WRITE ZERO DIRECT?
    Respond Y. This will write a new directory on the new system floppy,
in the left drive.
When the system responds with "SYS BUILT", type "SAVE SYS BUILD" to save
the new version of BUILD.

    If you built a system device, type "RUN RXA1 RXFIX" to  correct  the
new floppy's boot block.

OS/78
_____

    To install the handlers  into  OS/78,  one  must  only  type  a  few
commands. First, list the handlers in the system:
.SET HANDLER/L

    This will list the handlers in the current system. One of these must
be deleted in order to make room. For instance, the RL1 handler  can  be
deleted if you do not have a RL01.

    Copy the file "RXB.HN" to the OS/78 system  device.  Then,  assuming
that you are replacing the RL1 handler, install it with the command

.SET HANDLER RL1<RXB

    This completes the installation. The handler can be  used  with  the
names "RXB0" for drive 0, and "RXB1" for drive 1.

COS to OS/8 Conversion
______________________

    The handlers can be used, along with the COS-310 FILEX  program,  to
convert COS-310 files to OS/8 or OS/78 files. Also, OS/8 -  OS/78  files
can be converted to COS-310 files.

    To convert a COS file to an OS/8 file,  use  FILEX,  specifing  OS/8
ASCII output (option A). Output the file to RX drive 0. Then,  boot  the
OS/8 or OS/78 system, place the COS disk in  drive  one,  and  copy  the
file. For example, if the output was specified (to FILEX) as  "FILE.TX",
type the command:

.PUNCH SYS:FILE.TX<RXB1:FILE.TX

    This copies the file to drive zero, and compresses it.

    To convert from an OS/8 file to a COS-310 file, first copy it  to  a
COS system diskette, in drive one.

.COPY RXB1:<SYS:name

    Then, run the COS FILEX program, specifying OS/8  ASCII  input,  and
reading the file from drive zero.

    Further  information  on  FILEX  is  given  in  the  COS-310  system
reference manual.
