-*- Splitter v2.0 -*-
A >>SHAREWARE<< program by S.Coates & M.J.Matts
Shareware conditions
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
If you use Splitter and consider it useful enough to continue using
it then please consider making a donation to the authors. I would
suggest £10 UK pounds as a resonable donation. Any donations should
be sent to the address at the end of this doc file and thanks in
advance for anything..
Magazine & PDL Conditions
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Splitter may be distributed freely by any PD Library or BBS but it
may *NOT* be used on any magazine cover disk without permission from
the authors first, any magazine failing to comply with this request
will have action taken against them. Disk only magazines are free to
place Splitter on the disk without the authors permission on the
condition that a copy of the relevant edition is sent to the authors
in advance of publication.
Please do not remove any files from this archive if you intend to
distribute it further.
What files you should have
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
SPLITTER.TTP : Main file splitting/building program
SPLITTER.PRG : GEM shell for easy use of SPLITTER.TTP
SPLITTER.DOC : This file!
SPLITTER.C : Full ANSI 'C' source for SPLITTER.TTP
FILE_ID.DIZ : Description of SPLITTER for BBS's
BBS_ADS.TXT : BBS adverts.
If any of these files are missing please notify the authors stating
where you obtained the archive from.
And now about the program itself!
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Splitter was written after a request from Alan Woodcock (Desktop
Services) who wanted to be able to ship a 1meg+ scanned image file to
another machine via floppy disks, obviously the size of the file
presented a major problem, especially if it had already been packed
with LZH,ZIP or another archiver. Splitter allows you to overcome
this barrier by breaking the large file into smaller blocks, and then
rebuilding it to it's original form.
How to use Splitter.
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
The main Splitter program was previously written in GFA Basic which
made it an Atari specific program, for v2 it has been rewritten in C
using ANSI compliant code and has been successfully compiled without
any changes on the following platforms:
Atari ST - Lattice C 5.60
Atari ST - GNU C 2.4.5
MSDOS 6.20 - GNU C (32 Bit)
OS/2 2.1 - GNU C
Sequent Dynix/PTX 2.10
IBM RS/6000 AIX 3.2.0
This will now allow split files to be rebuilt on computers other
than Atari's. With the Atari ST release you have the added advantage
of an easy to use GEM interface which will make it much easier to
use.
The main display of the Splitter shell allows you to control every
feature of the program quickly and very easily. The following text
will describe each step which you should take for splitting or
rebuilding a file.
Setting a block size
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
There are 3 ways to set your maximum block size. One is to manually
enter the size in bytes, secondly you can click on either of the
buttons to increase or decrease the value by 1 byte and lastly by
double clicking on the buttons which will increase or decrease the
block size by 1024 bytes at a time. Please note that you can hold
the mouse button down to repeat the procedure and that a minimum
block size of 1024 bytes will always be assumed, that is you can
define any block size from 1024 to 9999999 bytes.
Splitting a file.
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Click on the 'SPLIT' button and use the fileselector to choose the
file to be split. The size of each split block will depend on the
setting previously defined.
Rebuilding a split file
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Click on the 'BUILD' button and use the fileselector to select the
*.000 file which will be rebuilt. Once selected you will then be
asked to choose the path for the file to be rebuilt into.
Checking a split file
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Click on the 'CHECK' button and use the fileselector to select the
*.000 file to be checked. No action will be performed apart from the
integrity of each split block being checked.

Updated version information
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
version 1.1 - Released (04/06/93)
o Changed selectable block sizes to be in 100k steps rather than 10k
steps, this made more sense as you can now split a large file into
a 720k block to save having too many split files for one large file!
o When re-building a file you can now select where you want to have
it rebuilt instead of it re-building automatically in the split
file folder.
o If you selected a block file and it was incorrect or corrupted you
could still click on the 'Rebuild' button even though there was
nothing to actually rebuild due to the error, this is now fixed.
version 2.0 - Released (29/03/94)
o Splitting routines now rewritten in ANSI 'C' to allow support for
split files on other platforms.
o New GEM shell written for the new Splitte program.
---- Happy file splitting ----
