RATFOR(1)

NAME

ratfor − rational Fortran dialect

SYNOPSIS

ratfor [ options ] [ files ]

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

Origin: System V

Remarks: Not supported on the Integral Personal Computer.

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.

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

The options are as follows:

−h causes quoted strings to be turned into Hollerith constructs.

−C copies comments to the output and attempts to format it neatly.

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

Ratfor is best used with fc(1).

−d compatibility mode for earlier versions of ratfor.

HARDWARE DEPENDENCIES

Series 500:

Fc(1) does not recognize ratfor.r files. Therefore, ratfor must be called directly.

The −h option should not be used.

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