萌新求助！看不懂源代码文件

Karoline0099

我第一次接触Fortran，因为学业需求，当时前辈留下了一个写好的.f90，我试着在我电脑上运行了一下，提示出错，但是我自己完全不知道怎么回事
有没有大神可以帮忙看一下这个文件，怎么才能成功运行起来？

1、给错误提示。2、我试了一下，编译连接没问题，可以运行但缺少输入文件。

你是不是选错编译器了？用的什么编译器？

第一句改为：integer,Parameter::line=364,sample=2048
原来的语句，sample是实型，gfortran不让它作为数组大小，ivf虽然会警告，但却不报错。

我没有用过啊，只是被告知要使用什么
一个叫做mingw-64w的
