Document Table of Contents

A to Z Reference

This section contains the following:

  • Language Summary Tables

    This section organizes the Fortran functions, subroutines, and statements by the operations they perform, and shows short descriptions of each routine. You can use the tables to locate a particular routine for a particular task.

  • The descriptions of all Fortran statements, intrinsics, directives, and module library routines, which are listed in alphabetical order.

    Certain routine groups, such as POSIX* routines and NLS routines, are in separate sections.

    NOTE:

    In the description of routines, pointers and handles are INTEGER(4) on IA-32 architecture and INTEGER(8) on Intel® 64 architecture.

    ifx does not generate code to run on IA-32 architecture.

The Fortran compiler understands statements and intrinsic functions in your program without any additional information, such as that provided in modules.

However, modules must be included in programs that contain the following routines. Note that the links in this list go to the relevant language summary table:

Whenever required, these USE module statements are prominent in the A to Z Reference.

In addition to the appropriate USE statement, for some routines you must specify the types of libraries to be used when linking.
