This manual describes the Fortran 77 language specifications as implemented using the MIPSpro Fortran 77 compiler. This implementation of FORTRAN 77 contains full American National Standard Institute (ANSI) Programming Language Fortran (X3.9-1978). It has extensions that provide full VMS Fortran compatibility to the extent possible without the VMS operating system or VAX data representation. It also contains extensions that provide partial compatibility with programs written in SVS Fortran.
The following documents contain additional information that may be helpful:
The MIPSpro Fortran 77 Programmer's Guide provides a description of the Silicon Graphics MIPSpro Fortran 77 compiler.
The MIPSpro 64-Bit Porting and Transition Guide provides information about improving program performance by using the optimization facilities of the compiler system, the dump utilities, archiver, debugger, and the tools used to maintain Fortran programs.
The MIPSpro Compiling, Debugging, and Performance Tuning Guide provides an overview of the 64-bit compiler system and language implementation differences, porting source code to the 64-bit system, compilation and run-time issues.
You can obtain compiler message explanations by using the online explain(1) command.
In addition to printed and online prose documentation, several online man pages describe aspects of the compiler. Man pages exist for the library routines, the intrinsic procedures, and several programming environment tools.
You can print copies of online man pages by using the pipe symbol with the man(1), col(1), and lpr(1) commands. In the following example, these commands are used to print a copy of the explain (1) man page:
% man explain | col -b | lpr
Each man page includes a general description of one or more commands, routines, system calls, or other topics, and provides details of their usage (command syntax, routine parameters, system call arguments, and so on). If more than one topic appears on a page, the entry in the printed manual is alphabetized under its primary name; online, secondary entry names are linked to these primary names. For example, egrep is a secondary entry on the page with a primary entry name of grep. To access egrep online, you can type man grep or man egrep. Both commands display the grep man page to your terminal.
