Systems/C++ is Dignus' C++ compiler product for the IBM mainframe. Systems/C++ compiler software allows users to develop mainframe C++ applications on a mainframe, or on UNIX and Windows workstations.

The Version 1.80 release is now available!

Version 1.80 of Systems/C++ includes an update to the popular STLport library, as well as a greatly improved code-generator, improving the runtime performance of C++ programs on the mainframe.

For more technical details about the new release, visit the "whatsnew" description.

Systems/C++ is an ANSI 98 compliant C++ implementation, and includes the industry-standard StlPort C++ library and Standard Template Library. Also, as with Systems/C, Systems/C++ provides a robust assembly language interface.

As well as OS/390, z/OS and mainframe Linux environments, Systems/C++ can operate in IBM compatibility mode - compiling IBM C++ programs for use in an LE runtime environment.

Systems/C++ is available as a native compiler for OS/390,z/OS, Linux/390 and z/Linux, or as a cross-compiler hosted on Windows, AIX, Solaris, FreeBSD and Linux.

Systems/C++ can be applied to many development tasks.

• Did you ever want to compile your IBM C++ programs under your workstation's build environment. Imagine compiling IBM C++ programs under Microsoft's Visual Studio. Systems/C++ makes that possible!

   

• Did you ever want to compile C++ programs for the mainframe and package them without worrying about run-time libraries. Systems/C++ makes that possible!

   

• Did you ever want to directly reference assembly language source from C++ code, or directly in-line assembly code in the middle of your high-level code? Systems/C++ makes that possible!

In short, Systems/C++ takes your development to the "next level!"

Features of Systems/C++ include:

• Complete 64-bit enabled compiler and library.
• ANSI 98 C++ compiler, and processor.

   

• Systems/C++ C++ libraries for OS/390, z/OS, Linux/390 and z/Linux, including the industry-standard STLport (no need to build your own.)

   

• Available as a native C++ compiler on OS/390, z/OS, Linux/390 and z/Linux, as well as a cross compiler on Windows/95, Windows/NT, Windows/2000, AIX, Linux, Solaris and FreeBSD.

   

• Generates formatted and commented ASM source, ready for assembly by Systems/ASM on OS/390 and z/OS, or the Linux assembler on z/Linux and Linux/390.

   

• Supports direct in-line assembly code - including system macros. Allows for access to registers via C++ variables for readily communicating data between ASM and C++ code.

   

• Optimized function entry and exit. Entry and exit macros can be tailored, on a per-function basis, or completely replaced by the user's own macros. The choice of base register can be changed on a per-compilation basis.

   

• IBM C++ compatibility mode; where the generated assembler source code can be freely mixed with IBM C/C++ objects.

   

• Native OS/390 and z/OS support:
  • Industry-standard STLport included.
     
  • Cross-memory mode (HASN != PASN != SASN).
     
  • Full access to OS/390 services via in-line ASM source.
     
  • Allow non-key 8, supervisor state and SRB-mode execution.
     
  • 24/31 bit AMODE.
     
  • Supports DISABLED callers (interrupts) with modified function entry and exit macros.
     

   

• z/Linux and Linux/390 support:
  • Industry-standard STLport for Linux/390 and z/Linux included.
  • Compiles with the Linux system header files, unchanged.
  • Generated objects link with any other Linux objects.
  • Can generate Linux assembler source on any supported platform.
  • Systems/C++ language extenstions supported, including direct inline assembler source.
