Fortran 66, Fortran 77 and Fortran 90 (95). The most common Fortran version today is still Fortran 77, although Fortran 90 is growing in popularity. Fortran 95 is a revised version of Fortran 90 which is expected to be approved by ANSI soon (1996). There are also several versions of Fortran aimed at parallel computers. DEC Fortran 77 Manual f77 Invokes the Digital Fortran 77 (FORTRAN-77) compiler. This command can also invoke other software components (such as preprocessors, or the ld linker), depending on which files or options are specified on the command line. The f77 command produces object code files in ULTRIX RISC or Digital UNIX Alpha extended coff This manual describes the PGI implementation of the FORTRAN 77, Fortran 90/95, and Fortran 2003 languages. Collectively, the PGI compilers that implement these languages are referred to as the PGI Fortran compilers. This manual is part of a set of documents describing the Fortran language and the compilation tools available from PGI. In 1977, a revised version of FORTRAN, FORTRAN 77, was completed (the standard was published in 1978). The next version is Fortran 90, which is a major advance over FORTRAN 77. It contains many new features; however, it also contains all of FORTRAN 77. Thus, a standard-conforming FORTRAN 77 program is also a standard-conforming Fortran 90 program. PROGRAMMING MANUAL FOR FORTRAN-77" Robert C. Beach Computation Research Group Stanford Linear Accelerator Center Stanford University Stanford, CA 94309 January 1992 . - Prepared for the Department of Energy under contract number DE-AC03-76SF00515. Printed in the United States of America. the first Programmer's Reference Manual was not issued until October 15, 1956, and the first Fortran compiler became available to customers in April 1957, running on the IBM 704, a 36-bit machine. called Fortran 77, and is the language level supported by virtually every Fortran compiler available today. Most vendors had Fortran 77 compilers This brief manual explains how to use the NUFFT suite for one, two and three dimensions. In each dimension, we distinguish between three types of problems: The NUFFT*d2f90 (Fortran 90) and NUFFT*d2 (Fortran 77) subroutines implement the type 2 transformations described in section 1. The calling sequences for the double Fortran Language Reference Manual CHAPTER 1 Introduction INTRODUCTION TO THIS MANUAL This is the common language reference manual for the Absoft Fortran 77, Fortran 90, and Fortran 95 implementations. Operating systems supported on the platforms include: Windows, Linux, and Macintosh OS X. Absoft Fortran compilers in these environments Fortran is the most widely used programming language in the world for numerical applications. It has achieved this position partly by being on the scene earlier than any of the other major languages and partly because it seems gradually to have evolved the features which its users, especially scientists and engineers, found most useful Pragma directives can be written in either C/C++ or FORTRAN 77/90. In C/C++, the syntax of a pragma directive is: #pragma apge cprog. Where: • #pragma is case-sensitive and must start in column 1, • apge is case-sensitive, • cprog is a control-program, and.
