Before You Begin |
The Fortran Library Reference describes the intrinsic functions and routines in the Forte Developer Fortran libraries. This reference manual is intended for programmers with a working knowledge of the Fortran language and the Solaris 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 creating and use, program analysis, porting, optimization, and parallelization can be found in the companion Forte Developer Fortran Programming Guide.
The following are the typographic conventions used in the text and code examples in this manual:

The Forte Developer product components and man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the Forte Developer compilers and tools, you must have the Forte Developer component directory in your PATH environment variable. To access the Forte Developer man pages, you must have the Forte Developer man page directory in your MANPATH environment variable.
For more information about the PATH variable, see the csh(1), sh(1), and ksh(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH and MANPATH variables to access this Forte Developer release, see the installation guide or your system administrator.
Use the steps below to determine whether you need to change your PATH variable to access the Forte Developer compilers and tools.
To Determine Whether You Need to Set Your PATH Environment Variable |
1. Display the current value of the PATH variable by typing the following at a command prompt:
% echo $PATH |
2. Review the output for a string of paths that contain /opt/SUNWspro/bin/.
If you find the path, your PATH variable is already set to access Forte Developer development tools. If you do not find the path, set your PATH environment variable by following the instructions in the next section.
To Set Your PATH Environment Variable to Enable Access to Forte Developer Compilers and Tools |
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your PATH environment variable.
Use the following steps to determine whether you need to change your MANPATH variable to access the Forte Developer man pages.
To Determine Whether You Need to Set Your MANPATH Environment Variable |
1. Request the dbx man page by typing the following at a command prompt:
% man dbx |
If the dbx(1) man page cannot be found or if the man page displayed is not for the current version of the software installed, follow the instructions in the next section for setting your MANPATH environment variable.
To Set Your MANPATH Environment Variable to Enable Access to Forte Developer Man Pages |
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your MANPATH environment variable.
