RATS is available for most UNIX-based workstations, including Sun, HP, IBM, MIPS, DEC and Silicon Graphics. It is also supported for DEC Alpha machines running OpenVMS, and Intel-based PC's running Linux. For most of these, RATS is shipped as C language source code, which must be compiled on the target machine with an ANSI-standard C compiler. The Linux version is also available as a pre-compiled executable.

The UNIX/Linux/OpenVMS versions support virtually all of the features offered in the DOS, Windows, and Macintosh versions. The only significant difference is that these versions currently do not include an interactive editor. Thus RATS is primarily a batch-mode only program on these systems. You can use any text-editor to create your RATS programs and view output.

Version 4.3 added the ability to display graphs directly to the screen on systems running X Windows. Earlier versions could only save graphs to disk in RGF (RATS Graph Format) files. Version 5 adds the ability to automatically save graphs directly into PostScript format (you can also still save graphs in our RGF format for viewing on PC/Mac systems running RATS, or for later conversion to PostScript using the separate RGF2PST utility).

System Requirements

• RISC-based CPU running UNIX or OpenVMS, or Intel 486 or Pentium-based CPU running Linux
• an ANSI-standard C compiler
• a 3.5" floppy disk drive capable of reading DOS format disks
