Now You Can Develop And Maintain 370/390 and
z/Architecture Assembler Programs
From Your Workstation

with the
Tachyon 390 Cross Assembler
and the
Tachyon z/Assembler

Now there is a cross assembler that takes you all the way there...
...and you'll never want to go back.

The assembler runs on:
Windows 95,98,ME,NT,2000,XP,
AIX, Linux (Intel/x86 and S/390)
and Solaris (Sparc).

The object runs on:
z/OS, z/VM, OS/390, VSE, TPF
Linux for S/390 and zSeries
and the Tachyon Operating System.

It's all about Speed, Compatibility, Productivity, and Savings.

The Tachyon 390 Cross Assembler and Tachyon z/Assembler are Fast:

Here is what one customer experiences:

“We can assemble an entire product (Space Recovery System) on a 400 MHz PC in 45 minutes and it takes over 3 hours to do the same on the P390. We are happy with development on the PC.”
Duane Reaugh
Manager, Technical Support
DTS Software, Inc.

And another customer reports reports that the Tachyon 390 Cross Assembler is almost 100 times faster than HLASM for VSE on a P390.

Supports the lastest High Level Assembler Language:

There is no need to compromise. Now you can develop real mainframe assembler programs on your workstation. We are not talking about simple date subroutines. We mean large programs that use every feature of the IBM assembler language. It’s all there, even most of the newest features of the High Level Assembler release 6. The Tachyon 390 Cross Assembler and Tachyon z/Assembler support:

The assembler can read source, copy and macro files in EBCDIC, ASCII or UNICODE. The listing file can be produced in EBCDIC, ASCII, or formatted for PCL (Hewlett-Packard compatible) printers. Object files can be produced in OMF, XOBJ or GOFF format and are ready to be linked and run on the mainframe or the Tachyon Operating System. Even an ADATA file can be generated that is so compatible, it can be used by IBM’s Program Understanding Tool (ASMPUT) of the HLASM Toolkit.

The Tachyon z/Assembler goes beyond IBM’s HLASM by reading GNU assembler source files and creating ELF object file format for building Linux for S/390 and zSeries programs. The Tachyon z/Assembler can even assemble the output of the GCC compiler and generate GOFF object files for use on OS/390 and z/OS.

Get your work done quicker:

If you like the mainframe development tools, you can practically recreate that environment on your workstation. With products such as SPF/Professional and the Tachyon 390 Cross Assembler or Tachyon z/Assembler, about the only way you will know that you aren’t using TSO is the response time. The Tachyon 390 Cross Assembler and Tachyon z/Assembler can even insert error messages right into your assembler source in the SPF edit screen.

On the other hand, if you want to take advantage of the many powerful tools available for workstation development, the Tachyon 390 Cross Assembler and Tachyon z/Assembler will integrate quickly into your environment. You can use the “make” utility to automatically rebuild only the parts of the system that have changed. You can use any of the workstation-based source code control systems to manage your mainframe source code. You can even integrate the Tachyon 390 Cross Assembler and Tachyon z/Assembler into your development environment, such as Microsoft Visual Studio, SPF/SourceEdit or IBM’s VisualAge TPF.

Reduce Costs for Mainframe Development:

Now there is no need to work off-hours to get your assemblies done. You can get instant turn-around even when the mainframe is at its busiest. You don’t even need to be attached to the mainframe to get your work done. All you need is the Tachyon 390 Cross Assembler or Tachyon z/Assembler and your source code on your workstation.

The Tachyon 390 Cross Assembler and Tachyon z/Assembler have enhanced assembler statement validation not available with the IBM assemblers. It can detect coding errors that could result in unwanted midnight phone calls. Don’t let errors in seldom executed code slip by your testing. Use the “LINT” feature on all of your code before you even start testing.

When you do start testing, the Tachyon 390 Cross Assembler and Tachyon z/Assembler can generate symbolic debugging information for your testing tools. There is even a direct interface to Cole Software’s XDC debugger and the Tachyon Operating System debugger, including support for long symbol names.

With the Tachyon 390 Cross Assembler
and Tachyon z/Assembler
there are no compromises.

No other assembler even comes close.
Don’t just take our word for it,
try it yourself.
