c++ - 使用寓言从Fortran 77转换为C++

Question

我只是想使用寓言将基本的helloworld.f程序转换为C++(以备以后使用更大的程序)。我收到一个错误，虽然说:

fable.read.Error: Missing END for PROGRAM:
  at hello.f(1):
  |      program HelloWorld|

我不了解，因为它可以编译并正常运行。该程序只是:

  program HelloWorld
  implicit none
     write (*,*) 'Hello, world!'   ! This is an inline comment
  end program HelloWorld 

有人看到寓言找到的问题吗？我以前从未使用过它，所以我只是想看看它是如何工作的。在此先感谢您的帮助!

我认为它不能解析end program HelloWorld。尝试将其更改为end program或仅更改为end。
更新:确实，在Fortran 77中，所有内容都必须以with just END结尾:

The END statement indicates the end of the sequence of statements and comment lines of a program unit ( 3.5). If executed in a function or subroutine subprogram, it has the effect of a RETURN statement ( 15.8). If executed in a main program, it terminates the execution of the executable program.

The form of an END statement is:

END

An END statement is written only in columns 7 through 72 of an initial line. An END statement must not be continued. No other statement in a program unit may have an initial line that appears to be an END statement.The last line of every program unit must be an END statement.
