between hard drives and across platforms. By allowing the user to select
any path name with a disk changing option, large files may easily be
split onto floppy drives, tape drives, etc.With the addition of the size
option any size device may be used to its full capacity.

Usage
-----
CHOPPER can be used from either the command line or from the full
intuition interface.
CHOPPER.EXE is the MS-DOS version of the progam, which can only be
used through the command line at this time.
Usage from the Command Line:
----------------------------
Usage to CHOP file:
CHOPPER [+C] [+R] [+D0] [+D1] S=# <input-file> <output-file>
Usage to JOIN file:
CHOPPER [+C] [+R] [+D0] [+D1] +J <input-file> <output-file>
OPTIONS:
+C ... This option is used to prompt the user for disk changes.
+R ... This option is used to read/write the split files to/from
the RAM: directory.
+D0 ... This option is used to read/write the split files to/from
the DF0: directory. This forces a +C to the options.
+D1 ... This option is used to read/write the split files to/from
the DF1: directory. This forces a +C to the options.
S=# ... This option is used so the user may specify the size of the
split files created (in kilobytes).
+J ... This option is used to join the split files back together.
FILES:
<input-file> : The full name of the file to split or the prefix
name of the files to join.
<output-file> : The prefix name of the split file to create or the
full name of the joined file.
EXAMPLES FROM SHELL:
1) To split a file onto the standard devices DF0: and DF1:
CHOPPER +D0 +D1 S=800 Big.Anim SplitAnim
2) To split a file from one directory to another:
CHOPPER S=800 hd0:Big.Anim dh1:SplitAnim
3) To rejoin a file from RAM: to the current directory.
CHOPPER +R +J SplitAnim Big.Anim
Usage from the Intuition Interface:
-----------------------------------
The intuition interface consists of a movable window containing two
string fields, one integer field, five checkbox gadgets and three butons.
The two string fields are for the input file and output file. You may
use the standard file requester to join these by clicking on the InFile
and OutFile buttons, respectively. Make sure that when joining files back
together the name does not include the '.#' suffix.
The integer gadget is labelled 'Size' and it used to set the size of
the output split file in # of bytes. This field is ignored when joining
files.
The following checkbox gadgets are used as follows:
RAM: - When activated chopper will send it's output to the RAM:
device (Same as the .
DF0: - When activated chopper will send it's output to DF0:.
Note: this function will force Disk Prompt to be active.
DF1: - When activated chopper will send it's ouput to DF1:.
If both DF0: and DF1: are activated chopper will use both as output
devices.
Disk Prompt - When activated this gadget will enable the prompts for
disks when Chopper starts a new file. This allows the
use of removable media devices as well as floppies,
ram, and hard drives.
Join - Will take a pattern from the InFile string and join the
associated files back into one.
Spliting and Joining files are done in much the same as they are from
the command line. When all options have been selected and fields are set
to the desired attributes, click on the GO TO IT! Gadget to send CHOPPER
to work. Chopper's Title bar will change to "Working..." and the InFile
and OutFile fields will be ghosted. Everything will return to normal when
CHOPPER has finished.
