Introduction
¯¯¯¯¯¯¯¯¯¯¯¯
Extract allows you to copy part of a source file to a destination file.
For instance it can be useful to extract a text from a program, a color
map from an IFF picture, the only numerical characters from a raw font,
and so on. If you have no idea on where the part of the file you need is
situated, you can seek it by using a file editor or the DOS command Type
with the H option.
The program can also be utilized to break in 2 or more parts a file that
is too big to be copied to a single floppy disk. Later on you can rebuild
the original file by using the DOS command Join.
System requirements
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Any Amiga.
Installation
¯¯¯¯¯¯¯¯¯¯¯¯
Copy Extract anywhere you want (I suggest the C: directory).
Usage
¯¯¯¯¯
The program can only be started from a CLI/Shell window with the
following form:
Extract <source> <dest> <start> [<end>]
where:
<source> = Source file name.
<dest> = Destination file name. It mustn't be the
same as <source>.
<start> = Start position: 0 <= <start> < file size.
<end> = End position: <start> <= <end> < file size.
It is equivalent to end-of-file if omitted.
Guarantee
¯¯¯¯¯¯¯¯¯
The program has been tested several times, but its reliability is not
guaranteed at 100%. I (the author) do not consider myself responsable for
loss or damage of data as consequence of the use of the program. Use
Extract at your own risk.
Copyright
¯¯¯¯¯¯¯¯¯
The program is CARDWARE, therefore it is freely distributable on
condition that it is always accompanied by this documentation. Both the
program and its documentation must not be modified in any way. If you
think Extract is useful, let me know by sending me a postcard or an
E-mail message.
