The Fortran User’s Guide describes the intrinsic functions and routines in the SunTM Studio Fortran libraries. This reference manual is intended for programmers with a working knowledge of the Fortran language and the SolarisTM operating environment.
This guide is intended for scientists, engineers, and programmers who have a working knowledge of the Fortran language and wish to learn how to use the Sun Fortran compilers effectively. Familiarity with the Solaris operating environment or UNIX® in general is also assumed.
Discussion of Fortran programming issues on Solaris operating environments, including input/output, application development, library creation and use, program analysis, porting, optimization, and parallelization can be found in the companion Fortran Programming Guide.

Read Chapter 6 in the User’s Guide. These are called class options. You must be superuser to do this. |
AaBbCc123 |
Command-line placeholder text; replace with a real name or value |
To delete a file, type rm filename. |
The symbol ∇ stands for a blank space where a blank is significant:

The FORTRAN 77 standard used an older convention, spelling the name “FORTRAN” capitalized. The current convention is to use lower case: “Fortran 95”
References to online man pages appear with the topic name and section number. For example, a reference to the library routine GETENV will appear as getenv(3F), implying that the man command to access this man page would be: man -s 3F getenv

This Sun Studio release supports systems that use the SPARC® and x86 families of processor architectures: UltraSPARC®, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems for the version of the Solaris Operating System you are running are available in the hardware compatibility lists at http://www.sun.com/bigadmin/hcl. These documents cite any implementation differences between the platform types.
In this document, these x86 related terms mean the following:
“x86” refers to the larger family of 64-bit and 32-bit x86 compatible products.
“x64’ points out specific 64-bit information about AMD64 or EM64T systems.
“32-bit x86” points out specific 32-bit information about x86 based systems.
For supported systems, see the hardware compatibility lists.
You can access the documentation at the following locations:
The documentation is available from the documentation index that is installed with the software on your local system or network at file:/opt/SUNWspro/docs/index.html on Solaris platforms and at file:/opt/sun/sunstudio12/docs/index.html on Linux platforms.
If your software is not installed in the /opt directory on a Solaris platform or the /opt/sun directory on a Linux platform, ask your system administrator for the equivalent path on your system.
Most manuals are available from the docs.sun.comsm web site. The following titles are available through your installed software on Solaris platforms only:
Standard C++ Library Class Reference
Standard C++ Library User’s Guide
Tools.h++ Class Library Reference
Tools.h++ User’s Guide
The release notes for both Solaris platforms and Linux platforms are available from the docs.sun.com web site.
Online help for all components of the IDE is available through the Help menu, as well as through Help buttons on many windows and dialog boxes, in the IDE.
The http://docs.sun.com/ web site enables you to read, print, and buy Sun Microsystems manuals through the Internet. If you cannot find a manual, see the documentation index that is installed with the software on your local system or network.
