f77

 
 Invokes the DEC Fortran compiler.  This command can also invoke
 other software components (such as preprocessors, or the ld
 linker), depending on what files or options are specified.  The f77
 command produces object code files in RISC (ULTRIX and DEC OSF/1)
 or AXP DEC OSF/1 extended coff format, and is described in detail
 in your DEC Fortran user manual.  (See also f77(1).)


 Format:


     f77 [options] filename [options]


 If you specify more than one option or filename, separate each with
 a space.  Some options include keywords.  For more information, see
 Parameters.


 Upon program completion, the f77 driver returns one of the
 following status values:
     0 - SUCCESS
     1 - FAILURE
     2 - SUBPROCESS_FAILURE (preprocessor, decfort, or ld)
     3 - SIGNAL


 If the environment variable DECFORT is set, the value is used as
 the name of the compiler to invoke.  If the environment variable
 TMPDIR is set, the value is used as the directory for temporary
 files.


 Your DEC Fortran kit contains a Help file in text format.  To
 search for information in this file, enter the following command to
 display the file:


    % more /usr/lib/cmplrs/fort/decfortran.hlp


 To search for a specific item, enter a slash (/) followed by the
 item.  For example, once the Help file is displayed, you can search
 for run-time error message number 138 by entering the following:


    /138
