Introduction

Contents

BeHA is a freeware compressor designed to handle the HA compressed archives under BeOS operating system. Is a terminal executable for BeOS R4 or upper on x86 platforms (Intel, AMD...). BeHA is a conversion of the public use program HA, created by me for my compressors comparison, because I found free the source code and none compressor of this format for the BeOS operating system.

BeHA is under the GNU General Public License or GNU/GPL. This mean that IT HASN'T ANY TYPE WARRANTY, that its distribution ITS FREE and OPEN, and that the SOURCE CODE is AVAILABLE to anyone that wants to use it (under e-mail request).

HA format compatibility

Contents

BeHA handle HA archives compatibles with version 0.999ß of the HA compressor, in Linux or DOS versions, or in versions baseds on its source code.

Command line syntax:

Contents | Commands | Modificators

BeHA <command and modificators> <archive> <files to compress>

The command must be before any modificator.

The archive doesn't require the extension. It mean that to create the archive "test.ha", is enough to write "test".

The files to compress with spaces must be under quotes:

"/Long Name/*"

BeHA use the BeOS nomenclature:

'*' mean all files.

'*.*' mean all files that have a dot in the name.

What BeHA doesn't have?:

Contents

BeHA is simply a recompilation on BeOS of the HA compressor, so it doesn't have some "details" that HA doesn't have or that any BeOS compressor must have:

· Icon - I don't know how to put icons on the BeOS programs :-).

· Fastest and more efficient compression methods - HA doesn't have these.

· An archive format more complete and enlargeable - The HA format is too simple.

· Save BeOS system specific data - I don't know how are these.

· Password protection - HA doesn't have it.

· VMultiple volumes - HA doesn't have it.

· A module to create self-extractable archive - HA doesn't have it.

· A version to the PowerPC BeOS (BeOS/PPC) - I don't have it and I can't compile it from the x86 BeOS (BeOS/x86).

For most of these things I need help, so I solicite help to anyone that wants to help me to convert the HA format in almost as common as RAR or ARJ :-)

System requirements:

Contents

BeHA has been compiled on a 200Mhz Pentium with BeOS R5 Personal Edition, and must be compatible with any machine that meet the system requirements of the BeOS/x86 system that have BeOS R4 or upper. If any incompatibility was found I will thank all the details about the fail to try to find a solution..

BeHA availability:

Contents

The new version of BeHA can be found in the Industrias O.S.G. web page. Also is available an information system about the new versions that must be requested with an empty e-amil to 636976463@correo.movistar.net putting as subject "BeHA mailing list".

Legal comentaries and gatitudes:

Contents

I want to thank to Harri Hirvola to do HA under the GNU/GPL, although it was on a very green status. I want also to than to Be Inc. that they make free a version of BeOS and its compatibility with the Linux programs source code.
