Introduction
Refer to the dbx Reference Manual for a detailed description of the debugger.
For information on interfaces to programs written in assembly language,
refer to the Assembly Language Programmer's Guide.
Organization of Information
This manual contains the following chapters and appendix:
• Chapter 1, “Compiling, Linking, and Running Programs,” gives an
overview of components of the compiler system, and describes how to
compile, link edit, and execute a Fortran program. It also describes
special considerations for programs running on IRIX systems, such as
file format and error handling.
• Chapter 2, “Storage Mapping,” describes how the Fortran compiler
implements size and value ranges for various data types and how they
are mapped to storage. It also describes how to access misaligned data.
• Chapter 3, “Fortran Program Interfaces,” provides reference and guide
information on writing programs in Fortran, C, and Pascal that can
communicate with each other. It also describes the process of
generating wrappers for C routines called by Fortran.
• Chapter 4, “System Functions and Subroutines,” describes functions
and subroutines that can be used with a program to communicate with
the IRIX operating system.
• Chapter 5, “Fortran Enhancements for Multiprocessors,” describes
programming directives for running Fortran programs in a
multiprocessor mode.
• Chapter 6, “Compiling and Debugging Parallel Fortran,” describes and
illustrates compilation and debugging techniques for running Fortran
programs in a multiprocessor mode.
• Appendix A, “Run-Time Error Messages,” lists the error messages that
can be generated during program execution.
