Overview

The development environment in Digital UNIX Version 4.0 is fully ANSI C/ISO C compliant; offers the programming features of both BSD and System V UNIX and is compliant with most current standards, including POSIX, XPG4, and XPG4-UNIX; features debuggers that support C, Assembler, FORTRAN (F77 and F90), C++, Ada, and connecting to /proc; supports shared libraries, threads, versioning; and has a fully optimized C compiler that produces extremely efficient code to exploit fully the 64-bit address space of the Alpha architecture.

In addition, Digital UNIX Version 4.0 supports internationalization, standard UNIX development tools such as awk, lint, make, and prof, and provides various run-time libraries such as C++ and FORTRAN.

The following sections highlight the major functionality in the development environment.
