Raleigh, NC - November 6, 2002: Dignus, LLC announces delivery of the world's first 64-bit compiler for z/Architecture . This major release demonstrates the company's commitment to its customers and the mainframe C and C++ community. Dignus, LLC is the first company to deliver complete IBM z/Architecture compilers and libraries with the general availability of Systems/C and Systems/C++ Version 1.60 today. "This delivery, while maintaining support for earlier architectures, fully exploits z/Architecture-allowing programs to execute in 24, 31, or 64-bit as well as allowing all dynamic storage to be allocated above the 31-bit 'bar'," said Dave Rivers, founder and President of Dignus, LLC.

In addition to major processor related enhancements, this robust software delivery also includes a
CICS C preprocessor and support for a number of ANSI 99 language features.

Important features of this delivery include:

• Complete z/Architecture exploitation by Dignus C and C++ compilers, with support for 24, 31, & 64-bit execution
  

• Complete z/Architecture exploitation using Dignus C and C++ libraries, allowing for the stack, heap and PRV to be allocated in 24, 31 or 64-bit storage, as well as supporting execution in 24, 31 or 64-bit addressing mode
  

• Implementation of the 64-bit capable Direct Call Facility, allowing 24 & 31-bit applications to extend their current functionality to exploit 64-bit storage
  

• Support for z/Linux code generation as well as compiler hosting
  

• Support for the UNIX Systems Services hosting of the compiler
  

• Implementation of various ANSI C99 C Language features including a complete ANSI C99 preprocessor
  

• Support for an MVS 3.8 compatible library
  

• CICS C language preprocessor
  

• Enhanced code optimization techniques improving performance
  

• Exploitation of all 16 floating point registers
  

• DSECT to C structure conversion utility

• A new compiler option to specify the generation of z/Architecture code. When specified, the compiler can generate code that can run in 24, 31, or 64-bit addressing mode, supporting all storage allocation in 24, 31, or 64-bit storage. When compiled with this option, various data types become 64-bits, including the long and pointer data types.
  

• Support for __ptr31 and __ptr64 pointer modifiers for z/Architecture and non-z/Architecture compilations, allowing interchange of pointers.
  

• Support for ALIGN4 and ALIGN8 parameters lists for function declarations allowing functions to be called from z/Architecture and non-z/Architecture functions.
  

• Implementation of a compiler AMODE option that specifies the generation of code that will run in ANY addressing mode, or a specified addressing mode of 24, 31 or 64-bit.
  

• Generates code for z/Linux and optionally runs directly on z/Linux as a host environment, while extending development platforms to include UNIX Systems Services(USS). This capability is in addition to the native hosts of z/OS, Linux/390, and the cross-development environments which include Sun, Windows, Linux, AIX, and FreeBSD.
  

• With this delivery, a complete ANSI C99 preprocessor as well as a majority of the ANSI C99 Language features are supported, including the _Bool type, declarations anywhere, declarations in 'for' statements, C99 diagraphs, variadic macros, and _Pragma among others.
  

• The addition of IBM C compatibility items, including pragma export and support for all IBM C built-in functions.
  

• New DSECT to C structure conversion utility, supporting 64-bit data types utilizing Systems/C extension to produce readable C structures. This utility further simplifies the task of writing Systems code in C.
  

• New CICS preprocessor for C based on CICS/TS V2R2 and CICS/ESA V4R1.
