efl

EFL(1)							      General Commands Manual							    EFL(1)

NAME

       efl - Extended Fortran Language

SYNOPSIS

       efl [ option ... ] [ filename ... ]

DESCRIPTION

       Efl  compiles  a  program written in the EFL language into clean Fortran.  Efl provides the same control flow constructs as does ratfor(1),
       which are essentially identical to those in C:

       statement grouping with braces;
	      decision-making with if, if-else, and switch-case; while, for, Fortran do, repeat, and repeat...until loops; multi-level	break  and
	      next.   In  addition,  EFL  has C-like data structures, and more uniform and convenient input/output syntax, generic functions.  EFL
	      also provides some syntactic sugar to make programs easier to read and write:

       free form input:
	      multiple statements/line; automatic continuation statement label names (not just numbers),

       comments:
	      # this is a comment

       translation of relationals:
	      >, >=, etc., become .GT., .GE., etc.

       return (expression)
	      returns expression to caller from function

       define:
	      define name replacement

       include:
	      include filename

       The Efl command option -w suppresses warning messages.  The option -C causes comments to be copied through to the Fortran output (default);
       -#  prevents  comments from being copied through.  If a command argument contains an embedded equal sign, that argument is treated as if it
       had appeared in an option statement at the beginning of the program.  Efl is best used with f77(1).
