Fortran 读取语句
新手问题，但我在任何地方都找不到一些好的 Fortran 文档。
我正在研究一个程序，作者使用读取语句来评估用户是否想要重新运行脚本。
代码是：
PRINT *,'Calculate again? .TRUE./T/t -> yes , .FALSE./F/f -> no'
READ *,answer
然后它使用逻辑变量answer来选择程序下一步要转到哪里。
上面的代码做了什么？
Newbie question, but I can't find some good fortran documentation anywhere.
I am studying a program and the writer uses a read statement to evaluate if the user wants to rerun the script.
The code is:
PRINT *,'Calculate again? .TRUE./T/t -> yes , .FALSE./F/f -> no'
READ *,answer
Then it uses the logical variable answer to select where does the program have to goto next.
What does the code above do?

可能应该是
READ *，answer从标准输入单元读取answer。代码输出“再次计算？.TRUE./T/t -> yes , .FALSE./F/f -> no”，然后读入
answer，我认为它被声明为逻辑变量。有关 Fortran 95 的文档，请参阅 http://en.wikipedia.org/wiki/Fortran_95_language_features。
Probably it is supposed to be
READ *, answerto read answer from the standard input unit.The code outputs "Calculate again? .TRUE./T/t -> yes , .FALSE./F/f -> no" then reads into
answer, which I suppose is declared as a logical variable.See http://en.wikipedia.org/wiki/Fortran_95_language_features for documentation of Fortran 95.
MSB是对的，我只是添加了评论中不适合的内容。
互联网上有大量优秀的 Fortran 资源。您可以使用官方标准，但通常更好的是编译器的文档。这个 http://publib.boulder.ibm.com/infocenter/comphelp/v111v131/index.jsp?topic=%2Fcom.ibm.xlf131.aix.doc%2Flanguage_ref%2Fassociatestmt.html非常好。
此外还有大量的课程和教程。只需谷歌“Fortran 初学者课程”、“Fortran 教程”或类似内容即可。
M.S.B is right, I just add what did not fit into a comment.
There are tons of good Fortran resources on the internet. You can use official standard, but better are usually documantation for compilers. This one http://publib.boulder.ibm.com/infocenter/comphelp/v111v131/index.jsp?topic=%2Fcom.ibm.xlf131.aix.doc%2Flanguage_ref%2Fassociatestmt.html is very good.
Also there are numerous courses and tutorials. Just google "Fortran beginner course", "Fortran tutorial" or similar.
