With Compression Plus, you can design your programs to utilize
available memory and disk space more efficiently by compressing files,
arrays (and other blocks of memory), and screen images to a fraction of
their original size, and decompress only the data you need when it is
needed. Our lightning-fast assembly routine will do the job quickly and
easily!
Features Include:
* Compression and decompression routines are written entirely
in hand-coded assembly language for the smallest, fastest
code possible.
* Unlike other products, we include more than six different
compression algorithms which are optimized for a wide range
of data:
- Static and dynamic Huffman encoding
- Optimized variants of Lempel-Ziv-Welch (LZW)
- LZ78
- Run-length encoding
- "Shrinking" and "Imploding" algorithms used in PkZip(tm)
by PkWare, Inc.
- Proprietary text screen compression algorithms
* Manually choose the compression algorithm you wish to use, or
tell our routines to analyze your data and automatically
select the most efficient algorithm for you!
* Supports files created with PkZip(tm) Version 1.10. With our
routines, you can create .ZIP files (including add, update,
and delete services), and extract files from .ZIP archives!
No need to SHELL to PkZip or PkUnZip!
* Includes a complete application installation utility. Reduce
your production costs by shipping your applications in a
compressed archive, requiring only a fraction of the
uncompressed disk space!
* All of our routines combined add only 30K to the size of your
.EXE files. Up to 64K of runtime memory is also required, but
we'll automatically use EMS (LIM Expanded Memory) or UMBs
(Upper Memory Blocks) if available!
* Includes a comprehensive manual, lots of example programs, no
extra charge for runtime royalties, free technical support,
and access to our 24 hours support BBS!
* Automatically detects the presence of a 386/486 CPU and
utilitizes highly-optimized code designed specifically for
them.
* Unlike other products on the market, Compression Plus handles
all of the file I/O and memory management issues for you
automatically. You simply "point" us to what you want to
compress and where you want us to put the compressed data,
and we do the rest!
* Free minor updates when downloaded from our BBS!
* Introductory price only $149 + shipping.
No where else will you find a more comprehensive collection of
easy-to-use compression routines written specifically for Microsoft
QuickBASIC 4.x, PDS 7.x, Visual BASIC for MS-DOS 1.x, Spectra
Publishing's PowerBASIC 3.0.
* Please note: PkZip and PkUnZip are trademarks of PkWare, Inc. EllTech's
demonstration utilites EtZip and EtUnZip are not to be confused with
PkWare's programs, but to be used only as a demonstration of the
capabilities of EllTech's Compression Plus programmers library.
