RATFOR(1)

NAME
ratfor - rational Fortran dialect

SYNOPSIS
ratfor [ option ... ] [ filename ... ]

DESCRIPTION
Ratfor converts a rational dialect of Fortran into ordinary irrational Fortran. Ratfor provides control flow constructs essentially identical to those in C:

statement grouping:
    { statement; statement; statement }

decision-making:
    if (condition) statement [ else statement ]
    switch (integer value) {
    	case integer:	statement
    	...
    	[ default: ]	statement
    }

loops:
    while (condition) statement
    for (expression; condition; expression) statement
    do limits statement
    repeat statement [ until (condition) ]
    break
    next

and some syntactic sugar to make programs easier to read and write:

free form input:
    multiple statements/line; automatic continuation

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

Ratfor is best used with f77(1).
