BLOKFILE.TXT

This text file describes the two programs:

          BLKTOFIL.BAS

          FILTOBLK.BAS

BLKTOFIL.BAS is used to convert CF83 Forth Blocks into a
standard BASIC ASCII file which can then be transmitted via
modem and uploaded to and downloaded from DELPHI, other such
services, bulletin boards, etc.

FILTOBLK.BAS is used to convert these files back into CF83
Forth Blocks for use with the CF83 Forth threaded interpreter.

The GENERAL PROCEDURE is:

     1.  One CF83 Forth programmer develops some application
         in CF83 using the Block Editor or some other editor. 

     2.  That programmer then uses BLKTOFIL.BAS to convert the
         application's CF83 Forth blocks to a BASIC ASCII file
         which is then uploaded to Delphi, BBS's, etc.

     3.  A second programmer downloads the BASIC ASCII file and
         uses FILTOBLK.BAS to convert it back to CF83 Forth
         blocks.

     4.  That second programmer then loads the blocks into the
         CF83 Forth threaded interpreter and runs the
         application.

These two programs are both hereby placed into the public
domain - you may freely distribute copies in any manner you
wish.

But, to make any real use of these programs, you need to have
at least the CF83 Forth Master Disk, available from:

          BDS Software
          P.O. Box 485
          Glenview, IL 60025-0485      

To use BLKTOFIL.BAS, simply RUN "BLKTOFIL" and follow the
prompts.  You will be prompted to put the disk containing the
CF83 Forth Blocks into Drive Zero and the disk on which you
want the file to be created in Drive One.

The CF83 Blocks Disk is not altered by BLKTOFIL.BAS, but we
recommend that you backup the disk before running BLKTOFIL.BAS
anyway.

The file can be created on any BASIC disk having a sufficient
number of free grans, but we recommend that you use a formatted
blank disk for safety.

To use FILTOBLK.BAS, simply RUN "FILTOBLK" and follow the
prompts.  You will be prompted to put the disk containing the
file into Drive Zero and the disk on which you want the CF83
Forth Blocks to be re-created in Drive One.

The file MUST be one that was originally created from CF83
Forth Blocks using BLKTOFIL.BAS.  The file disk is not altered
by FILTOBLK.BAS, but it is recommended that you backup the disk
before running FILTOBLK.BAS anyway.

It is STRONGLY recommended that you use a blank formatted disk
for the CF83 Forth Blocks disk, because FILTOBLK.BAS will
overwrite any existing data which happens to be on that disk at
the block locations.

The versions with the Manual on Disk also include a READER
program which allows viewing the manual on the screen and/or
printing the manual to your own printer.

A CF83DEMO disk is available for $3.00 - the same demo can be
downloaded free from Delphi - but note that the demo will NOT
allow loading of CF83 Forth Blocks - you need the master disk
for that.
