efl - Extended Fortran Language
efl [ option ... ] [ filename ... ]
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 pro- grams 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).
