RATFOR(1) — HP-UX

NAME

ratfor − rational Fortran dialect

SYNOPSIS

ratfor [ options ] [ file ... ]

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 per line and automatic continuation of lines

comments:
# this is a comment.

compiler directives:
directives beginning with a dollar sign ($) in column one are passed through to the compiler unchanged.

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

return expression to caller from function:
return (expression)

define:
define name replacement

include:
include file

Options

The following options are supported:

−h Cause quoted strings to be turned into Hollerith constructs as, for example, 27H.

−C Copy comments to the output and format them neatly.

−6c Normally, continuation lines are marked with an & in column 1. The −6c option makes the continuation character c and places it in column 6.

Ratfor is best used with f77(1).

DEPENDENCIES

Series 300
Options can be passed to ratfor through f77(1) by using the −W option specifier.

Series 800
The −6x option must be used for successful automatic line continuation.
