ratfor - rational Fortran dialect
ratfor [ option ... ] [ filename ... ]
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 [n] next [n] 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 The option -h causes quoted strings to be turned into 27H constructs. -C copies comments to the output, and attempts to format it neatly. Normally, continuation lines are marked with a & in column 1; the option -6x makes the continuation character x and places it in column 6. Ratfor is best used with f77(1).
