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 2.30 release is now available!

Version 2.30 of Systems/C++ features complete C++14 support as well as several C++17 features.

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

Systems/C++ is an ANSI 98, C++11 and C++14 compliant C++ implementation with many C++17 facilities supported. It includes the industry-standard 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, even on a workstation!

Systems/C++ is available as a native compiler for OS/390,z/OS and z/Linux, or as a cross-compiler hosted on Windows, AIX, Solaris, Solaris x86, HP/UX, Mac OS X 386, FreeBSD and Linux.

The documentation is available as .pdf file. And, you can request a 30-day trial of Systems/C++ to examine yourself.

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 or Eclipse. 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, 11 or 14 C++ compiler, and pre-processor.

• Systems/C++ C++ libraries for OS/390 and z/OS.

• Available as a native C++ compiler on OS/390, z/OS and z/Linux, as well as a cross compiler on Windows, AIX, Linux, Solaris (SPARC), Solaris (x86), HP/UX, MAC OS X 386 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.

• 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, and can be debugged with IBM debuggers.

• Native OS/390 and z/OS support:
  • 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 support:
  • GNU C++ compatibility, uses the system-provided headers and runtime.
  • 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.

Also - you can compile your own source! We've provided a web-based compilation mechanism to submit source and see the output from the Systems/C++ compiler (DCXX), along with the generated assembly language source.
